Getting Rid Of Annoying Fret Buzz

Look to the strings first. You may need to change them. Are they accumulating a film? (You may need to look on the underside to see

all the dirt you have on them.) There are a handful of products designed toextend the life of your strings, but if you want to go the economy route,simply wiping them down with a slightly damp cloth will be better thannothing.

Do you see dirt and grime building up on the fret board? (Minor, but if you'recleaning for grime, you might as well clean this surface during stringschanges.) You may want to clean this using a slightly damp cloth or a goodguitar cleaner. Some people recommend using the finest grade of steel wool

to abrade extra tough dirt off your fret board. I haven't had to go this far yet,and would urge caution to go easy on the elbow grease as to not scratch thefinish on the wood.

Long sweat and dirt buildup can eventually damage glue joints and warp yourinstrument (this would be after a long period of exposure without anymaintenance). I'm by no means an avid "guitar-polishing guy" but theoccasional cleaning of the fret board will extend its life.

If this doesn't fix your problem, the solution may require the expertise of anexperienced technician. There are some things you should do to pinpoint the locationof your buzz, but I'd never recommend someone grab their tools and try to adjust aguitar on their own. Learn from someone with experience and your guitar won'tbecome a field casualty.Check to see if the buzz is consistent across the length of the neck (from openstrings to the frets with small spacing towards the body of the instrument).

Pick each string without fretting any notes. Fret each string at the first fret and move towards the body. You may not

need to successively fret each position, but if you're compulsive about yourinstrument

Make a note as to where the buzz appears and where is goes away. If thebuzz stays from the open strings and doesn't go away even when you'refretting the highest pitched frets, the problem is likely in your bridge/saddleassembly. Are there any loose parts? You may need to have a technician workon this area. See if they'll let you view the process. I've gleaned a lot of maintenance knowledge by being present and asking simple question whilesomeone worked on my instruments. (Don't get in the way, technicians willtolerate your presence and questions, if they aren't annoyed by you're beingthere)

If you pinpoint the buzzing to the section of your neck closer to the body:

You may need to have your strings saddles adjusted up so they will be fartheraway from the first frets they come across. If you do this yourself, try to

make your adjustments in slight increments so you don't raise your actionmore than you need to. If the height of the saddle won't compensate enough,a truss rod adjustment is probably needed (see below).

There may be a fret, which needs to be sanded slightly to eliminate aninconsistent span. Don't make this adjustment yourself. If you go too far, the

mutilated fret will become permanently sharp in pitch.If the buzzing is closer to the middle of the neck or towards the nut: Inserting a slight shim under the nut can raise the strings high enough to

eliminate the strings unwelcome contact with the frets. This might be difficultif you have a glued in nutbut those of you who put up with the lockingvariety, can easily take the nut off and insert a small piece of paper or foilunder the nut. Remember to take it in increments; it's hard to play thoseneoclassical licks with high action.

Your neck may need to have the truss rod adjusted. This is a rod of metal,which runs the length of your guitar neck. By turning it to the left or right,you cause the wood to bow in or out. Of all the adjustments mentioned, this

is the most dangerous and should definitely be handled by a technician. If youturn the rod too far (as in of a turn) you can splinter the neck. Here is astep to watch and learn. Minute adjustments can make a big difference in thebow of the neck.

Some adjustments may cause other adjustments to be needed to preserve the actionby the way. Cleaning the neck and getting a new set of strings might solve yourproblems. If you're a strummer and using light strings, maybe you should raise theaction and move up to a heavier gauge of string. Don't be afraid to take yourinstrument to a technician. You can learn quite a bit for future maintenance.

What are the differences between Gain, Overdrive and Distortion?

Using Gain, Overdrive, and Distortion can either add or detract from your overallguitar tone, so it's a good idea to know the differences between them. Technicallyspeaking, There are several definitions to these terms, but we are only going to dealwith the audio Aspects, or how it sounds to your ears.Gain is usually defined as an overall boost in your signal without any added tonalcoloration. It is usually expressed in decibels such as "Gimme a 3dB boost on thatkick drum." Adding more gain is basically just amplifying the signal so it cut throughthe mix or can be heard over a loud drummer.Overdrive, as it has come to be known as, is a smooth, warm, slightly distortedsound, generally associated with the sound made by cranking up a tube amp. It is fatand dynamic, allowing you to vary your tone just by the way you play. Overdrivepedals can come close to giving you that tube overdrive sound, probably the mostpopular being the Tube Screamer.Distortion can be defined as anything from a fuzz tone to a full-on, notched-outmidrange, death metal wall of noise. It is a hard-edged sound with as manyvariations as there are players. Digital distortion has a more metallic, raspy soundwhich works well for heavy metal, grunge, or reliving your 80's hair band days.Analog tube distortion gives a good, all-around rock tone, such as the sound of aMarshall stack cranked to 10.The key to all this is to listen and experiment and let your ears be the final judge.

Knowing the differences and how to use them will go a long way to helping youdefine your own signature tone.

Optimizing Guitar Playability

Playing guitar is a highly personal experience. Every player has different needs, andthat is why setting up your new guitar becomes a matter of personal taste. Wegenerally recommend taking your new ax to a qualified luthier for a proper set-up.Although most guitars play great right out of the box, some need just a little bit of tweaking to make them really perform.Ultimately what you are trying to achieve is:1. Good Action (the least possible distance between the string and the frets withoutbuzzing or rattling of the string against the fret).2. Balanced, even, electrical output on each string in all pickup positions.3. Smooth, accurate tuning action and the ability to stay in tune after bending a noteor using the tremolo.4. Last, but certainly not least, killer Tone!

Keep in mind though, that some of these goals are mutually incompatible. Forinstance, really light strings and really low action don't allow a guitar to sustain orsound fat, compared to the same guitar with heavier strings and higher action.Finding that optimal playing "zone" is sometimes a matter of compromise. Knowingthat, here are some tips that can help you achieve guitar nirvana.Strings:

Experimenting with different brands is great, but once you a find a brand and gaugeyou like, stick with it. Your guitar will thank you for it. Constantly changing stringgauges usually involves adjustments to the neck, which can be a time-consumingpain, and wouldn't you rather be playing?Wiping your strings down with a clean cloth after playing can extend their life andyour wallet.If you are breaking alot of strings at the bridge, the most likely cause are burrs thatdevelop on the string saddles. A light sanding and polishing is all that is needed tosmooth these out. Take your guitar to a luthier if you don't feel comfortable doingthis yourself.Tuners:

I can't say enough good things about Sperzel locking tuners. They are worth theirweight in gold. While I wouldn't recommend installing them on a vintage Strat; for anew, out-of-the-box guitar they work wonders. They offer rock solid tuning, andactually improve sustain by adding more mass to the headstock.If you're going with stock tuners, make sure all screws are snug but not too tight. If it still feels sloppy or will not hold the pitch, replace them.Pickups:

There is a phenomenon regarding guitar pickups called "magnetic interferance." Thisis where the magnetic field generated by the pickup actually impedes the vibration of the string, causing a dull, lifeless sound. Generally you want to get the pickups closeenough for good output, but not so close as to choke the string. Fender recommendsaround 5/64" clearance from the top of the pole piece to the bottom of the stringfretted at the last fret. You can check this with ]automotive type feeler gauges.


4/19

Action:

This is going to be a general recommendation which may not apply to everyone'splaying style. First, check the relief, or amount of bow in the neck. Put a capo at thefirst fret then hold down the 6th string at the last fret. Using a feeler gauge, measurethe gap between the string and the 8th fret. Factory spec for Strats and clonesshould be around .010" Next, check the bridge saddle height.Factory spec at the 17th fret should be 5/65" for strings 1-4, 3/32" for strings 5-6.Another really cool trick is to adjust the saddles to follow the radius of thefingerboard, meaning the middle string saddlesare higher than the outside saddles.This allows the strings to follow the natural curve of the fingerboard and makes for asmoother playing neck.These are just a few recommendations for getting the most out of your guitar. Again,if you don't feel comfortable with doing this yourself, take it to your favorite luthier.Watch and learn, and pretty soon you'll be doing it yourself. Also, if your'e a do-it-yourself kind of person, pick up a copy of The "Guitar Player's Repair Guide." It too isworth its weight in gold.

Drum Set Assembly 101

Now that Christmas is over and the bicycles have been put together, the new clotheshave all been worn and the chocolate covered cherries have been eaten, it's time toput together the drum kit you bought for Junior.Getting familiar with the kit There are many different drum set combinations, the most common being the 5-piece kit. We will be assembling a kit consisting of these shell components:1 - 16" x 22" Bass Drum1 - 10" x 12" Ride Tom1 - 11" x 13" Ride Tom1 - 16" x 16" Floor Tom1 - 5.5" x 14" Snare DrumAnd these hardware components:1 - Bass Drum Pedal1 - Snare Drum Stand1 - Hi-Hat Stand2 - Tom Holders3 - Floor Tom Legs2 - Cymbal stands (one straight and one boom)Let's Begin:

Start with the bass drum. Locate the bass drum hoops, which are the largest of thehoops, and are usually the same color as the drum kit. You will also need to find the

hoop claws and the longest lugs in the bag of misc. hardware you will receive withthe kit. You should have 16 of each (8 for each hoop). Set the bass drum so it is flaton the floor. A determination will need to be made as to which is the front head andwhich is the "batter side" head. With most drum kits you will have the manufacture'slogo on one of the heads, which goes on the front of the drum. Determining the frontof the bass drum is much easier. The side closest to the bass drum legs (or spurs) isthe front.Place one of the small washers on each of the long lugs and insert through the holein the claw. They will only work one way, so try one before you put them all together.


5/19

There are usually 8 lugs per side, so place the correct head on the drum, place thehoop on the head (it should fit on the outer rim of the head) and hang the claws onthe hoop, threading them into the bridge lugs on the drum. Finger-tighten the head,turn the bass drum over and repeat. NOTE: often times a small pillow placed in thebass drum removes over-ring and adds punch.Next the Toms. Locate the smallest of the toms and find the 2 heads and 2 chromehoops that are the same size. There will also be 12 short lugs and 12 washersnecessary for this drum kit. Place the head on the drum and the hoop on the headlining up the holes in the hoop with the bridge lugs on the drum. Place a washer oneach lug and insert through the hole, and thread into the bridge lugs. Finger tightenonly. Turn drum over and repeat. Note: Sometimes a top and bottom (batter headand bottom head) will be sent. The bottom head will always be thinner, usuallytransparent.Using the same technique to do the other ride tom and floor tom, we should have allof the drums with heads. If the snare drum is not assembled, use the sametechnique for it as well.Let's put it all together

Again let's start with the bass drum. Set the drum so that the 2 spurs are close tothe ground, and the chrome mount located near the middle of the drum is pointingup. Set the legs so that they are holding the bass drum securely, and not able torock sideways (as if rolling). Firmly tighten the spurs.Find the 2 tom holders in the package of tubular hardware. Each of these should fitinto one of the holes in the top of the bass drum. Insert them one at a time, andpoint them out, so you can slide the toms on without banging them into one another.As for the correct position, there is no right or wrong way to set them up. You willneed to try different ways that work for you.The Floor Tom is next. You will notice about 1/3 of the way up from the bottom thatthe floor tom has 3 chrome mounts. These are the leg mounts, and you will find 3steel legs in the hardware box. They are approximately 18" - 24" in length and havean odd bend at one end, with a rubber foot. Insert these into the assemblies, andadjust to a comfortable height.The snare drum stand is the stand with the shortest legs, and it will have a set of 3"arms" which when folded down securely hold the snare drum. It will have a largeadjustable nut under the basket, which you will use to tighten the 3 arms to hold thebottom of the snare. Another knob will adjust the height of the snare. Adjust it to acomfortable position. the 3rd adjustment is the angle adjustment. It adjusts theangle of the snare drum. Again, adjust it for comfort.The bass drum pedal attaches directly to the bass drum hoop on the back side.Attach it and lock it down securely with the adjustment knob.The hi-hat stand may be in 3 pieces.. a smaller solid shaft threaded at one end, a

tubular piece with the cymbal cup and the tripod stand with the pedal. The smallershaft threads into the nut on the stand assembly, then the tubular piece slides overthe shaft, and into the stand assembly. A felt washer goes into the cymbal cup, andthe cymbal clutch tightens with a wing nut to the shaft.This leaves the 2 cymbal stands, which both use the same size tripod base. Thestraight stand will be in 2 or 3 telescopic sections, and the boom stand will have anaddition piece with a hinge in the center. This allows you to place your cymbal closerto the drums.

Remember that the important thing to remember is to HAVE FUN! There is no rightor wrong way to set your kit up. Try different things, and HAVE FUN!

Drum Tuning

Now that your kit is assembled, it's time to make it sound like a drum kit insteadof...well, instead of how it sounds. While there are many techniques to achievedifferent types of sound and tone, virtually all of the pro's agree that you must haveeven head tension to eliminate unwanted ring and overtones. In other words, thetension should be the same at each tuning lug. Sound easy? Well, due to modernmanufacturing techniques and better heads, it is easier than it was a few years ago.However, it still requires some practice to develop your touch and ear.Let us begin...Kick Drum:In the previous tech tip, we mentioned putting a pillow into the bass drum as a wayto help with the overtones and tuning of the drum. While its possible to achieve agood punch without it, most folks (at least other band members and recordingengineers) prefer to have a solid "thud" sound with a slight over ring. Whether youchoose to use a pillow or not, the tuning procedure is still the same.Start by tightening the lugs until they are all finger tight. You will notice wrinkles inthe head around the edges. Choose any tuning lug and tighten it 1/2 turn. Then, godirectly across the head and do the same with that lug. Continue in this fashionaround the drum until the wrinkles are gone and you hear a tone when you tap onthe head. Once you begin fine-tuning, you will want to turn the lug no more than 1/4turn. When tuned properly, you should hear the same pitch when you tap on thehead in front of each lug. (Approximately 1" in from the rim.) Different shells sounddifferent depending on how high or low they are tuned, so experiment with thetuning.Snare Drum:

Because there are so many different types of materials used to construct snaredrums, including wood, steel, copper and brass, the snare can be tuned to anamazing number of tones and textures. Again, experiment with different tunings tofind the tone that works for you.I prefer a very tight, fat snare sound. To achieve this I start with the bottom snarehead. Using the same technique as the bass drum, make sure the tension is even asyou go around the head. I like to have the bottom head as tight as possible, whichgives the snare a tight snap when I hit it. Use your own judgment.The top head I tend to keep quite a bit looser, in order to "fatten" the snare sound. If you still have too much over ring, a small piece of duct tape will help to alleviate this.Place it approximately 1" from the rim of the snare, directly across from you (this willkeep you from hitting that spot with your sticks).Toms:Even tension on the top and bottom heads is critical for good tom tone. You maywant to take each drum off the mount to tune the bottom head (using the sametechnique as above). Find a pitch that sounds good to your ear, and try to tune thedrum to that pitch.Again, there is no right or wrong tuning for your kit, as long as it sounds good toyou. It will take a while to tune your kit, so don't get discouraged. The best advice Ican give you is to use small increments when you begin to fine-tune the drums. 1/4

turns are usually more than enough.One last tip. Placing the drum flat on a carpeted surface can also help when you are

just learning to tune the drum. This dampens the other head, letting you hear justthe head you are tuning.

Cleaning your CymbalsTo clean or not to clean, this is the question for many drummers when it comes totheir cymbals. Some players believe that a certain amount of grime and grit andsmoky residue adds to the character of the cymbal. No doubt that a certain barroomneglect may give your cymbals a certain roadhouse ambience. But for those who areinterested in extending the life of their cymbals and keeping them shining likeshining disks of pure sonic gold under the stage lights, heres some helpful tips.Many new cymbals are sprayed with a protective coating to keep them fromtarnishing in the store, so your cymbals may need less cleaning during the first 6months, depending on use. During this time, a solution of warm water and liquiddishwasher soap will clean fingerprints, dirt and grime. As your cymbals age, werecommend a professional cleaning cream to remove stick marks and tarnish. Put asmall amount onto the surface with a soft cloth and rub in the direction of the tonalgrooves, until the metal appears through the film. After the polish has dried to ahaze, buff gently with a clean, soft cloth. Clean only a small section of the cymbal ata time. Always avoid using any abrasives, such as steel wool, wire brushes, scouringpads or metal cleaners that contain abrasives. These products will scratch thesurface of your cymbal.

Tips for Multi-Track Recording

There are many things to consider when you are in the market for a recorder. First,what sound quality do you need? Are you making recordings for friends or to submitto the music industry? Another thing to consider is the number of tracks you needand the number of simultaneous recording tracks available. If you are only recordingone person and don't intend to submit your tape, you don't need anythingfancy...perhaps just a small multi-track tape machine for building songs track bytrack will do. These little tape machines generally use cassettes, which also makesthem easy and affordable. But it's good to have certain features, such as a pitchcontrol for changing the speed of the tape, and a high speed mode that providesmore tape for the sounds being put there and hence better quality recording.With this type of recorder, there are tricks that the digital machines are just nowbecoming able to do, like being able to have a song recorded with an instrumenttrack in reverse. This is easily achieved by ejecting the cassette and reinstalling itupside down, then recording the track while all the other instruments are playing inreverse, then just flip the tape and listen back.Besides the great little tricks you can do with tape machines, some say they arepreferable to digital recorders simply because they have tape, which lets you get ahotter signal and greater frequency response than you get with digital machines.When selecting a cassette tape for your recorder, you want the best sound qualityyou can possibly achieve, so, a cassette not over 45 minutes, and normal to highbias is going to work the best. One generally thinks longer is better, but a shortercassette will have an advantage often overlooked -- the tape is shorter, but it is alsothicker, and has more available material to more securely hold the magnetic fields

created by the tape heads. Thicker tape, moving across the heads faster, is the idealsituation.Have you ever noticed that sound quality that is lost when listening back to bouncedor "ping-ponged" tracks? Every time you re-record a track, since you're recordingyour recording, you lose a little. Here's a simple way ping-pong your analog tracksand keep the quality up. All you need is a digital VCR (most are digital after the mid90's). The tracks you decide you'd like to bounce to another track can be mixed andsent to the inputs on the VCR. It will digitally record them to the VCR. Then just sendthem back into the tape recorder onto a single track. They may not be quite as goodas your original tracks were, but they will be better than if bounced from one tapemachine to another.One of the most important things to know about recording to tape is that you wantto saturate the tape to give the recorded tracks their best possible quality. That'swhy tape machines generally have meters with a red area at the peak end. Whenrecording, you want the needle as near or just into the red zone as possible, withoutpinning at the top. In other words, you want to be as close to distortion level aspossible, without actually getting distortion. If you run it too safely, keeping it belowthe red zone completely, you'll avoid distortion, but not have as rich a recording asyou could have. The trick is to get familiar with your machines, so you know howhigh the needles can run without getting distortion.

Tips on Digital Recording, And Reasons for Liking It

You've recorded your rhythm guitar and bass tracks. You want to add a steel drumtrack but discover that the steel drum is grossly out of tune (as they often are). Withmost digital recorders, this is no problem. The recorder's speed can be changed tomatch the steel drum or keyboard or whatever. After the instrument is recorded, themachine can be returned to its original track speed with everything in tune.One of the things you learn to love about a digital recorder is not having to waitwhile tapes rewind or fast forward, watching the counter so you don't run past thepoint you want to stop at. Digital machines relocate automatically, instantly. Themachine just draws its information from a different place, rather than physicallyhaving to go there.Since most machines allow for different sample rates, they can be adapted foroptimum sound quality but less recording time, or lower resolution but extendedrecording time. This makes a digital recorder flexible, great for recording singlesongs at max quality, and also capable of recording long concerts withoutinterruption. Lower the sample rate and record on two tracks continuously for hours.On lower-end tape machines, punching in can be a problem in that it can be heardon the tape. Low end digital machines perform punch ins in a millisecond so everypunch stays silent on the recording.

Tabletop digital studios may seem to have only simple controls compared to analogmixing boards. Each button, however, can call up several menus that give youcontrol choices that can equate to those provided by a sophisticated mixing boardwith jillions of knobs.Most digital recorders can be used to step time for sequencing and be made to runthe scenes in light shows, or switch the effects on most digital mixers.Many digital recorders use zip disks or some similar removable media rather thaninternal hard disks. This makes them especially easy for collaborating. If you and


9/19

your buddy in Wisconsin have the same machine, you can mail zip disks back andforth. You don't have be around each other at all to make records together.Storing your digital recordings is tidier than storing tape. Tapes don't liketemperature extremes, or high humidity, and they get brittle after a few years.Digital recordings can be put stored on Zip Disks, Jaz disks, or CD ROMs that storebetter longer.

Speaker Impedance

The simplified explanation: Impedance is the tendency of a circuit to resist the flowof AC electricity and is measured in ohms. As the impedance goes up, it's harder forthe electricity to get through. A good analogy would be to water flowing through apipe. As the pipe diameter gets bigger, the water flows through it more easily. Thebigger the pipe, the lower the resistance or impedance.An amplifier's output transformer is designed to work with a particular impedancelevel (or more than one if it has switchable settings). Matching the correct speakerimpedance to the amp transformer is important. If mismatched, the transformer andother amp components can be damaged. Most speakers used today are either 4, 8,or 16 ohms.The more technical explanation: Impedance is the combination of reactance (whichchanges with frequency), and resistance (which does not change with frequency).Thus the speaker's impedance actually changes depending on the frequency of thesignal it is receiving. However, speakers are generally rated at a standard frequencylevel, resulting in the uniform 4, 8, and 16 ohm ratings.It's when you wire several speakers together that things get freaky. Adding twospeakers together, for example, can result in different impedances. It all depends onhow they are hooked together, in series or in parallel. Two 8 ohm speakers wiredtogether can result in 16 ohms (in series) or 4 ohms (in parallel). Here's why. Inseries, all the current is flowing through them one after another; thus, they

represent a larger impedance than a single speaker, the sum of their individualimpedances. If you wire them in parallel, the current has two different paths tochoose from and will split up evenly between them (assuming the speakers have thesame impedance). Thus, the total impedance will be less than the impedance of either single speaker. The formula for finding the impedance for speakers wired inparallel is the product of the two speaker ratings (8 x 8 = 64), divided by the sum (8+ 8 = 16). So two 8 ohm speakers would result in 4 ohms (64 divided by 16 = 4).Wiring parallel is the only way to add speakers together without adding reactiveloads.

Four FAQs for Beginning Bass Players

1. How are basses tuned?Four-string electric and upright basses are tuned in perfect fourths, E A D G from lowto high. Five-string basses commonly add a low B, but some add a high C instead of the low B. Six-string basses usually have both the high C and the low B. Seven-stringbasses add an F# to the six-string layout. Eight-string basses are like 12-stringguitars. There's an extra string added to each of the four standard strings, with thesecond set tuned an octave higher. 12-string-basses add two "octave" strings to thepair, making 4 sets of three strings.2. What is the difference between J-pickups, P-pickups & Soapbars?


10/19

The P in P-pickups stands for Precision Bass. They are made of two single coilpickups that are offset so they each pick up vibrations from two different strings. Thesignal is combined before it reaches the volume and tone controls. Each single-coil iswound in opposite directions to reduce hum. Basses usually have one P-pickup.The J in J-pickups stands for Jazz Bass. They are made in one piece that picks upvibrations from all four strings. J-pickups are single coils, and J-bases usually havetwo of them: one near the neck and one by the bridge.Soapbar pickups owe their name to their shape. These one-piece pickups are abouttwice as wide as J-pickups, and can be wired as either single-coils or humbuckers.3. What's the difference between bass strings?

There are two main flavors of bass strings: roundwound and flatwound. All woundstrings are made by wrapping layers of wire around a core wire. Roundwound stringsuse a round wire as the wrap, flatwound strings use a flat ribbon wire. Roundwoundstrings deliver brighter sounds, but can emphasize squeaks. Flatwound strings havea duller sound, with less extra noise.Flatwound strings tend to keep a more consistent tone longer. Here's an extra tip:You can rejuvenate your roundwound strings by boiling them in vinegar or milddetergent solutions. It really works.4. What is Biamping?

Biamping splits the signal from the bass preamp using a crossover. The highs aresplit from the lows and each is sent to a different power stage in the amp, and toseparate speaker cabs. Low frequencies require more power to deliver the samevolume, so this is ideal for situations where you have one cab with smaller drivers (4x 10) for the highs and another cab with meatier speakers (4 x 15) for the lows.

A MIDI Note

Many folks get confused about the purpose of a midi connection with regards to whatis transmitted. MIDI is a control language of 1's and 0's. It is used to sendinformation from one device to another (like from a keyboard to a sound module).One of the most misunderstood ideas with MIDI is the idea that audio is transmittedfrom the MIDI ports. MIDI ports aren't set up to be used as sound outputs (you can'tsend your keyboard's audio to the computer through the MIDI ports). What doescome out of a MIDI port is a stream of data consisting of 1's and 0's.What MIDI does is send command information from one device to others. Think of atelevision remote control. Does any of the programming you see and hear originatefrom your handheld remote unit? No. All the remote does is tell the television whatto show and how loud the volume should be (and perhaps some more advancedfeatures like picture in picture....would that be called a multitimbral television???)

Your MIDI controller simply sends what note should sound, perhaps how loudly, whatpatch or parameter to use, etc.. MIDI can be confusing, and there are new protocolsbeing developed all the time, but beginning with a good understanding of what itdoes not do can help make the learning curve an easier thing to overcome.

What's the difference between a tube amp and a solid-state amp?

The simple answer is that a tube amp uses one or more vacuum tubes to amplify thesignal, while a solid-state amp uses solid-state electronics (diodes, transistors, etc.)


11/19

to amplify the signal. On paper and in theory these two implementations should yieldidentical result, but in actuality the difference is usually noticeable.But the simple answer fails to answer to the complexity of the issue. Many amps arenot simply tube or solid-state, but mixes of both kinds, called "hybrids." This usuallymeans that they have a tube preamp stage, employing vacuum tubes in the toneshaping circuitry, but use solid-state circuitry for the power section. The hybrids arecloser to full tube amps in response and tonal warmth, but purists will still find adifference between the two. Tube amps are generally more expensive in initial costand to operate (because you need to replace the tubes occasionally), and solid-stateamps are generally less delicate and more reliable. Many players, however, feel thattube amps yield a warmer, more musical tone and better distortion.Yet another wrinkle is tube emulation circuitry. Many amps and preamps havesophisticated circuits designed to act like tubes, and as in all things, some are betterthan others. The newest develop in amps are the modeling amps, which not onlyemulate the tone and response of tubes, but of specific tube amps. These are ingeneral pretty exciting amps, but again, some are better than others at gettingspecific models, and in maintaining the sounds through a range of volume levels.Another point to make about tube amps is that bigger is not always better. You getthe distinctive tube sound most when the amp is cranked up enough that the tubesare saturated or nearly saturated. For this reason, it is often better to choose a lowerwattage amp over a higher wattage amp, depending on how and where you play. Bythe time you crank up your 60 watt amp enough to saturate the tubes to get just theright level of distortion, you could be blowing your audience out the back door. Itmight have been better to choose a 20W amp that lets you get your saturated tonewithout the ear-killing decibels.

How to Make Orchestral Samples Sound More Realistic?

Samples won't ever sound exactly like real orchestral instruments. But they cansound fairly close. Here are a few helpful principles to remember.Be sure to play the samples within the range of the actual acoustic instrument. Usephrasing and dynamics appropriate to each instrument. MIDI volume can addexpression to phrasing. Don't sustain wind instrument samples beyond a windplayer's breath capacity. Ranges and idiomatic instrumental usage can be found inorchestration books. Avoid playing anything on a sampled instrument that can't beplayed on the real instrument.Vibrato can be problematic. When a sample with natural vibrato is played more thana half-step above or below the note at which it was sampled the vibrato speed will beinconsistent, especially with wind instruments. In such instances, use sampleswithout vibrato, which can be added via LFO or pitch-bend wheel.In an orchestra, instruments occupy a given place on a stage or in a room. Use monosamples, and pan instrument sections to a consistent location. Reverb can helpsimulate front-to-back placement, as wee as add hall ambience. Examples of orchestral seatings can be found in some orchestration books.Samples can be recorded with various mic placements and effects processing.Maintain consistency as much as possible; effects processing can help.Orchestration books are invaluable. Books on MIDI orchestration are even more tothe point.

Which recording format is best for a home studio? *Each format has its advantages and disadvantages. Decide which one most closelyfits your needs, and then check out the features of various makes and models.Digital multi-track recorders get your music onto tape quickly and easily, plus they'reportable. Archiving your work is inexpensive. However, they have no cut and paste

editing or built-in audio processing. Punch-in recording writes over the originalmaterial. Making backups requires multiple recorders. Mixdown may require anexternal mixer.Stand-alone hard-disk recorders are capable of detailed editing, and they offerimmediate access to any location. Usually, a mixer is built-in. On some units,automated mixing, onboard effects, and/or timecode capability may be included. Andthey're portable. But some use data compression, and the editing screen may besmall. Archiving media is more expensive than digital tape. On some machines,punch-ins and bouncing are destructive; on others, they can be undone.Computer-based hard-disk recorders have the advantage of a large screen forediting. There are many high-quality software plug-ins for processing. Punch-ins andtrack bounces are non-destructive. Automated mixing is built-in. Most recordingsoftware also includes MIDI sequencing. However, a system can be expensive,including a powerful computer, an audio card, software, and an archiving media. Andit's not portable.Mini-Disc multi-track recorders are very affordable, portable, and include a built-inmixer. They offer some editing capabilities, but not as extensive as those on hard-disk or computer-based systems. Unfortunately, they use data compression, whichincreases with each track bounce, diminishing the sound quality. Backups can't bemade.Analog tape recording is less of an option these days. The sound of a high-endanalog tape recorder can't be beat, but the cost is high. Cassette recorders are OKfor capturing an idea quickly, but their sound quality is far below that of a digitalsystem.MIDI sequencing offers detailed editing, but it's restricted to electronic soundsources, so vocals or acoustic instruments can't be recorded. However, most MIDIsequencing programs include some audio recording capability, so the two formatscan be easily integrated.Many home studio owners use combinations of the above, such as a digital multi-track recorder coupled with audio editing software. Don't forget to budget in amixdown deck, whichever is appropriate: CD recorder, 2-track DAT recorder, or 2-track cassette recorder.

Easy Steps to Making Music On Your Home Computer

Any computer purchased in the last few years has the basic hardware for makingmusic. Computers with a hard drive smaller than 2Gb and a CPU slower then 100mhzis going to limit you to a few tracks at best. The bigger and faster your homecomputer, the more powerful your recording capabilities. Besides your computer, allyou need a microphone and software, and you're ready to record.Multi-track recording software is relatively easy to use. You don't need a sciencedegree to figure them out. Many programs are designed specifically for regularmusicians, and most offer a minimum of 8-track recording. Some programs comeequipped with full MIDI capabilities, virtual drum features, and multi-effects.


13/19

Actually recording is as easy as loading your software into your computer, pluggingyour mic into the sound card, and playing. Soloists can record one rhythm track,then record another lead track while your previous track plays back into yourheadphones, then add vocals on a third track.You can keep adding as many tracks asyour computer or software can handle.Most software lets you add effects on each track. A word to the wise: even thefastest computers start bogging down with too many simultaneous effects in realtime. Usually these 'bogs' will sound fine when you mixdown, when the processorcan handle extra effects because it isn't fixed to real time.Computer noise can be a pain when recording. The easiest thing to do is to put yourcomputer under your desk. Better yet, buy extra long cords for all you peripheralsand stick your computer in the next room.Of course you'll want to pick up a few cool extras. Perhaps a better sound card,superior mic, a mic mixer and preamp, and maybe a MIDI keyboard. And then you'llneed to burn your own CDs....

What are speaker crossovers?

Single speakers don't have a flat frequency response over the entire range of audiblefrequencies. That's why most cabs contain more than one speaker. The biggestspeaker is the woofer. It's for the low frequencies. The smallest, the tweeter, isdesigned to project high frequencies. The third speaker is for mid-range. Speakercabinets have a crossover built in to prevent these speakers from overloading.A speaker crossover is a filter system that takes the incoming audio signal and splitsit into chunks that each speaker can handle. If you have a woofer and tweeter, thenthe crossover has a lowpass and highpass filter. A third bandpass filter handles themid-range frequencies.

Which guitar effects are better: Single-effect stomp boxes or multi-effectspedals?

Multi-effects devices offer several effects in one package and blend usually blendeffects into presets or patches. There are a lot of cool multi-effects pedals out therethat give you a bigger bang for your buck...if you're looking at a dollar-per-effectratio. After all, some sacrifices have to be made to squeeze all those multi-effectsinto a small box and keep the price low.Individual, dedicated effect pedals often deliver superior effects with a wider rage of adjustabilitybut they cost more on a per/effect basis. In other words, you cantypically get more sonic quality and more variations on a single- effect pedal. Somelittle multi-effects pedals deliver some very nifty, high-quality sounds and someediting ability. It really comes down to personal taste, and which types of effectssound best with your music.Here's the bottom line: If your music requires multi-effects, then you need awhopping multi-effects pedal. But if you're only going to use a few effects, you maybe better served by dedicated stomp boxes. In the end, the music will tell youexactly what it needs.

Expanders and Noise Gates


14/19

Expanders are dynamic processors that increases the dynamic range of a signal.They make loud sounds louder and soft sounds softer. They're like an amplifier with avariable gain control, and the gain is controlled by the level of the input signal.Expanders are used by musicians to produce more extremes in recordings that havea limited dynamic range. This gives the music more intense dynamics.Noise gates are usually used to eliminate unwanted noise and hiss which wouldotherwise be heard when an instrument is not being played. The noise gate'sthreshold needs to be at the precise point so unwanted noise falls below it, and heinstrument's complete notes can be heard.Expanders and noise gates should be near the end of the effects chain, so noisecreated by other effects can be "gated" when you're not playing. I place my delayand reverb effects after the noise gate so their sounds trail off naturally.

About Equalizers

Equalizers boost or cut specific frequencies in a signal. The most common equalizersare tone controls. They tailor your sound to suit your music. Bass and treble knobscontrol a lowpass shelving filter and a highpass shelving filter. Lowpass and highpassfilters remove a portion of the sound spectrum. But shelving filters just pump up orreduce one portion while leaving the rest alone.There are also 'mid' controls found on3-band equalizers. This 'mid' is sometimes called a peaking or bandpass filter.Graphic equalizers provide more flexibility and control than tone controls, and they'reeasy to use. A graphic equalizer is a set of filters that allow you to control theamount of boost or cut in each frequency band. Controlled with sliders, thefrequency response of the equalizer resembles the positions of the sliders, that's whyit's called a 'graphic' equalizer.A graphic equalizer uses a set of bandpass filters that are designed to completelyisolate certain frequency bands. Each filter in the graphic equalizer has the sameinput. Their job is to only allow a small band of frequencies through.

Graphic EQ's are great for sound reinforcement and 'tuning' rooms. With a graphicequalizer that covers most of the audio spectrum, you can adjust your EQ so thatyou have a consistent sound at every venue.For instruments, stomp-box equalizers are great for delivering a both a volume boostand changing tone for solo excursions.Parametric equalizers give you the most flexibility, but are a bit more difficult to use.Unlike graphic EQ, that only lets you set the amount of boost and cut, parametric EQallows you to also set the center frequency and the bandwidth. With practice, youcan apply some boost to make a guitar cut through the mix, or to get a big, fullsound.Parametric EQs can eliminate feedback by using a lot of cut (also called a notch

filter) positioned right at the frequency that is feeding back. You might be able tocontrol the feedback with a graphic EQ, but if its bands are wide, you'll be cuttingmore of the sounds than you wanted. Parametric lets you fine-tune the cut, so youdon't lose the good stuff.Many amplifiers have 'presence' knob that boosts the mid to high frequencies. Thiscontrol is supposed to make your instrument sound like it is actually in the room onrecordings. It also helps an instrument slice through a muddy mix.

Compressors & Limiters

Compressors reduce a signal's dynamic range. It does this by reducing the gainwhen the signal level is high, making louder passages softer, and the dynamic rangesmaller. It is used in audio recording, production work, noise reduction, and liveperformance applications.

When signal levels get too high when recording, there will be distortion. Compressorsand limiters provide protection against sudden transient sounds that could distortyour sound or damage your equipment. It is also used for cutting tracks andadjusting the mix. It can smooth volume changes, adjust the dynamic range andbalance of a track.Compression can also increase an instrument's sustain. It amplifies the incomingsignal to maintain a constant level, so after twanging a string, a little compressionwill preserve the string's sound. While adding sustain to your arsenal, compressionalso reduces your dynamics, making it difficult to accent notes and phrases. Be coolabout compressing for the sake of sustain.If you need to have a signal's level controlled by a different signal, it is called'ducking' (it 'ducks' a signal out of the way) or cross limiting. Here's an example:While music is playing, using the microphone will cause the level of the music to dropso that it's easier to hear the singer. When mixing in the studio, a ducker can also beused to make certain instruments pop out of the mix.A 'de-esser' is a limiter that monitors only a specific frequency range. It only reducesthe level of frequencies in a selected range. This allows you to reduce unwantedsounds.When using a compressor with other effects, many players put it first in the chain.First, it gives you a good signal to work with. And when the compressor is on and theoutput level is increased, the noise will be amplified along with the instrument'ssound. Other effects can introduce more noise, so if the compressor is placed afterthose effects, it will end up amplifying their noises, too.

What is a Chorus effect?

Chorus effects can make a single instrument sound like a group of players. It adds arich, lush, shimmering quality to your sound.Here's how it works: when 2 people play the same song together, there is naturallysome delay between the sounds they produce. The pitch of the instruments can alsodiffer a bit. This is exactly what the chorus effect does. A delay line is used to get theslight delay, and by varying that delay, the pitch is slightly detuned. The result is therich, shining sound of two instruments playing at almost the same time.Chorus is commonly used with acoustic electric guitars to fatten up the sound andgive it extra sparkle. There are a variety of cool chorus units available as dedicated

stomp boxes, multi-effects units, or studio processors

What is a Delay?

Delay is one of the simplest effects out there and one of the most valuable. A littledelay can bring life to dull mixes, widen your instrument's sound, and even allow youto solo over yourself. Delay is the also a cornerstone of other effects, such as reverb,chorus, and flanging.


16/19

Delay is created by taking an audio signal and playing it back after the delay time.The delay time can range from several milliseconds to several seconds. Most delayshave a control that allows you to repeat the sound over and over, and it becomesquieter each time it plays back.Long delay times can open up some cool possibilities. Once you get over a second,you can virtually loop on the fly. Just pay a riff, then play over that riff while itsrepeating. You can actually solo over yourself when you don't have a rhythm player.A slapback delay has a very short delay time, usually between 30 and 100milliseconds. Most folks consider a longer delay an echo.Multi-tap delays allow you to create more complex patterns. Taking outputs frompoints within the delay line is called 'tapping'. The amount of delay between thevarious taps can be different. You can set the multi-tap delay to follow the rhythm of a song, or create amazing textures.Ping-Pong delay bounces between the left and right channels of a stereo signal. Ituses two distinct delay lines, each driven by an input. This produces two outputsignals, that create the classic 'bouncing' sound when panned hard left and right.

What are Phase Shifters & Flangers?

Phase shifters (or phasers) and flangers get their sound by creating one or morenotches in the signal's frequency. The notches are created by filtering the signal, andmixing the filter output with the input signal. The filters can control the location,number of notches, and width of the notches.Most phase shifters start with a simple filter, then add more filter stages to createmore notches. A stereo phaser uses two filters with notches at different frequencies.You can also create more complex sounds by mixing the outputs of the two filters.This can give you virtually endless sonic possibilities. From subtle rotating-speakereffects, to swirling, edge-city sounds from classic 60's guitar solos, phasers can be avery useful addition to any player's arsenal.Flangers produce the unmistakable jet-engine "whooshing" sound. Basically a type of phasing, a flanger creates a set of equally spaced notches in the audio spectrum.Phasing also uses notches, but multiple filters and user controls create randomspacing.

What do I need to record a CD with my computer??

We can list only the most basic components here. The following items can get youstarted.First, of course, you need a computer and a CD Burning program. There are anumber of good programs for both Macs and PCs.

There are two types of computer-based CD-recording (CD-R) units, SCSI and IDE. ASCSI CD-R is preferable because it's significantly faster, and it's less likely to fail dueto inability to transfer information with sufficient speed. IDE devices are usually, butnot always, fast enough, so get a SCSI device if you can.If you don't already have a SCSI interface on your computer, you'll also need a SCSIadapter card. Preferably, get an adapter that converts a PCI slot to SCSI; adaptersthat convert ISA slots are much slower.You'll need a hard drive with at least a gigabyte of usable space. CDs hold about


17/19

650Mb of data, but more is needed to handle the buffers in the recording software.Actually, two gigs of usable space are better, because you may want room for someaudio processing software plug-ins. Ideally, use a separate hard drive for your CDrecording.An audio interface is needed to get the audio into and out of the computer. Someaudio interfaces have analog inputs/outputs (I/Os), some have digital, and othershave both. Digital I/Os transfer the highest quality sound, by far. You may want bothanalog and digital I/Os - the digital I/O to record DAT tapes and CDs, the analog I/Ofor LPs and live recording. Also, PCI cards are superior to ISA cards, because theyare faster and susceptible to fewer hardware conflicts. Many audio interfaces alsoinclude CD Recording software.CDs sample at 44.1kHz. If your audio source was recorded digitally at 32 or 48kHz,you'll need to convert the sample rate to 44.1. Some soundcards can resample inrealtime, a fast and efficient solution. Some recording software can convert thesample rate by resampling the data that was recorded onto the hard drive. This canbe time-consuming, depending on the speed of the computer. Outboard resamplersare quick and effective, but more expensive. Obviously, if your source was recordedat 44.1kHz, you don't have to convert the sample rate.One more item is needed - a blank recordable WORM CD. WORM stands for WriteOnce, Read Multiple. It works just like a standard CD, and you can play it in any CDplayer.We haven't even scratched the surface of CD recording here, but we hope you nowhave an idea of what you'll need.

How to Get Rid of Single Coil hum without Getting Rid of Single-Coil Tone

Turn up your Strat (or any guitar equipped with standard single-coil pickups) andyou get a certain amount of hum and buzz, especially if playing under flourescentlights or near anything that creates a strong electromagnetic field. If you find this

sound hideously irritating, as many do, you might consider a guitar with humbuckingpickups. That's the extreme alternative...sort of like throwing the baby out with thebath water, because you get rid of the hum problem, but you also get rid of thattwangy, out-of-phase tone that single-coils get. The classic Fender tone, as it couldbe described.One way to beat the problem (still fairly radical) is to go active. With an activepreamp system in your guitar and a set of such pickups as Duncan Live Wiires, youcure the problem.But there is yet another solution, short of trading in your guitar or routing it out tomake room for humbuckers or active electronics. There is a group of pickupsdesigned to be hum-cancelling or "bucking," but which retain the essential single-coilsound. Seymour Duncan makes several. The "Classic Stack" has the dual coils of ahumbucker, but they are stacked so that the pickup has the dimensions of a singlecoil. It also retains the sound of a single coil, but without the hum. Their Vintage Railpickup is another that accomplishes the same mission, single-coil sound without thehum. Another pickup that is growing in popularity is the DiMarzio Virtual Vintage.Fender itself has several new designs that you can use as pop-in replacements onyour Strat. These are Lace Sensors and Vintage Noiseless. Most of the LaceSensors get a humbucker sound, but the Gold is designed for a vintage tone, aglassy, bell-like sound with crisp highs. Even closer in tone to your vintage singlecoils are Fenders new Vintage Noiseless pickups. In this case, Fender's noiseless


18/19

technology has very successfully minimized the noise while retaining the tone.This isn't an exaustive list, but long enough to show you that there are alternativeways to keep your single-coil equipped guitar "as is" vintagy, but with sweet silence,rather than buzz, between the notes.

What compression settings are appropriate for recording electric bass?Since the electric bass has a wider dynamic range than many instruments,compression is often applied in order to maintain a more even volume level and tomatch the dynamics of the kick drum. When peaks are reduced, the entire bass partcan be boosted in the mix without adding distortion.The settings depend upon both the music and the playing style of the bassist. It'snecessary to listen to the part and adjust the compression settings to obtain thesound you want. If the compressor has an input level, adjust it to get a nice hotsignal, but not loud enough to clip.The threshold level determines the maximum level - signals louder than thethreshold are reduced in volume. At 0dB, only the loudest signals (peaks) are

compressed, retaining most of the natural dynamics of the player. Settings between-2dB and -5dB are often used; when even more compression is desired, a thresholdof as much as -10dB or even -15dB might be chosen.The ratio setting determines how much the signal is reducSince the electric bass hasa wider dynamic range than many instruments, compression is often applied in orderto maintain a more even volume level and to match the dynamics of the kick drum.When peaks are reduced, the entire bass part can be boosted in the mix withoutadding distortion.The settings depend upon both the music and the playing style of the bassist.

The higher the ratio,the more the signal is compressed. A 2:1 ratio cuts the output of any signal abovethe threshold in half; a 3:1 ratio reduces a signal above the threshold by 2/3. A ratioof 3:1 is a good place to begin in your search for the optimum ratio. 4:1 is alsowidely used, but occasionally a ratio as high as 10:1 will suit the sound.The attack setting determines how quickly the peak is reduced. Slower attack timesallow the initial transient of the note to come through, for a punchier sound. If theattack is fast, all sharp peaks will be cut, and the part will be smoother. A mediumattack time of 20ms to 40ms is a good starting place.The decay time determines how quickly the compression goes away. If it's set toolow, it may compress a quieter note that rapidly follows an above-the-threshold note.A medium setting is good - fast enough to be ready for a quiet note, not so fast thatit boosts noise that occurs between notes. Between 125ms to 250ms is usuallyappropriate for bass.A compressor may allow you to select between hard-knee and soft-knee. Set onhard-knee, the compressor waits until the signal crosses the threshold, then it


19/19

reduces the signal at the specified ratio for a punchy sound. With soft-kneecompression, the ratio gradually increases as the signal approaches the threshold,resulting in a more natural feel and a wider dynamic range.If the output level is equal to the level of the peaks of the uncompressed signal, theoverall loudness will be higher. However, cheap compressors may add noise whentheoutput level is raised, so it may be preferable to boost the volume at the mixingboard. Adjusting one setting affects other settings. For example, an adjustment tothe threshold may require an additional adjustment to the ratio. Keep at it until youget the sound that fits.

Proper Care and Feeding of Tube Amps

First, you should try to make a habit of firing up your amp in Power/Standby modefor at least one minute before pounding the current completely to all tubes. This way,when the tubes get the full jolt of electricity, the plates are nice and warm. Hotcurrent hitting cold tubes is one of the worst things that can happen to a tube amp.Using the warm-up procedure can really extend the life your tubes. Switching theamp to standby for breaks also helps extend tube life. There are very good reasonstube amp manufacturers put standby switches on their amps. Using them properly isthe best thing you can do for your amp.You can tell if youre firing up your amp properly when youre quietly strumming yourstrings, waiting for the tubes to come on-line. If you have a fully audible signal andhear the notes clearly the instant you hit the switch, your doing the right thing.Some players recommend changing tubes almost annually. Ive owned tube amps foryears and have never yet changed or had a tube go bad. Actually, moderately worntubes sound better than new ones, and if properly cared for, just keep soundingbetter and better. I have to give credit to the folks at Mesa Boogie for teaching methese tube amp tips nearly 20 years ago. (Note: Mesa Boogie still offers this advicein their new owners manuals).

Phantom Power...No Big MysteryThe only person who need even think about phantom power is he who is equipping astudio and purchasing a board and mics, or the performer who wants to use acondenser mic on stage. What phantom power does is reside in the board (or in aseparate supply box) and power condenser mics (the high-end, serious recordingtype condenser mics). It's nice to have a mixing board with phantom powercapability. Otherwises you need an outboard supply box (these come in various sizesfrom single channel boxes up to eight or more channels), and that means anadditional expense and more hassle.Is phantom power better? It's all electricity, but one could consider it a more stable

source than a battery which eventually runs low on juice.Who else might benefit from phantom power? Bassists and guitarists who are usingactive D.I. boxes. Some of these units (such as the Sansamp) can be run onphantom power if connected to a board that provides it. Saves money on batteries,or saves you the hassle of plugging in a power supply, and phantom power won'tdisappear into the night as battery power can.
