This is a very simple buf fered split ter project . You can use it to create twoequal outputs for your guitar or another pedal. This is handy for running astereo amplif ier setup, split t ing a single signal into two ef fects pedals, or anyof several other applicat ions in which you need to have two equal, buf feredoutputs. The circuit consists of a simple t ransistor input buf fer that feeds apair of parallel op amp-based output buf fers.

From an EE perspect ive, this isn't a perfect circuit . From a guitar player'sperspect ive, it works exact ly as advert ised with no problems.

Project PDF includes schemat ic, parts list , build info, layout , and tonert ransfer artwork.

nice work!

Thanks!

This is an older project f rom CircuitWorkshop, but I realized I'd never posted ithere.

Another way :

Or (less noise)

Nice and useful. I think a phase switch can be an easy add to one of theoutputs, but ... it worth it?

Sorry to resurrect this post but if I was to put a volume pedal af ter one of theoutputs of this split ter, would it also af fect the volume of the other output?

I don't think so.

Re: Simple Buffered Splitter28 Apr 2012, 23:14 Stratocaster-Sam

I'll give it a go, see what happens. Not exact ly a cost ly build, and I'm sure it 'llcome in handy at some point .

Thanks.

Should this eliminate ground loop issues with 2 amps? Or do I needt ransformers.

Re: Simple Buffered Splitter10 Aug 2012, 09:53 Nocentelli

I think that if the outputs share a direct ground connect ion, there is thepossibilit y of ground loop issues.

Why not direct couple the emit ter follower and opamp follower stages?Save t ime in assembly, parts cost and circuit complexit y.
