Special subjects unit- amps the pros and cons of digital, solid state and valve and how they are designed and made

A guitar amplifier is a electronic device designed to amplify the electrical signal of an guitar so that it will produce sound through a speaker. These amps are usually designed and kept within a wooded cabinet, which pretexts the speaker and the amp, it self from any knocks and dings. This also allows the player to keep the amp in good working order and allows for easy handing when transporting the amp. A amp may be created in two ways to case the amp. One is called a guitar head and contains only the electrical part to amply the sound f the guitar and that other is called a combo which housed both the wiring and the speaker in one combined system hens the term (combo),

Most guitar amplifiers can also modify the instrument's tone by emphasizing or de-emphasizing certain frequencies and adding electronic effects, typically distortion and reverb. The input of modern guitar amplifiers is a 1/4" jack, which is fed a signal from a electro-magnet from the pickup of a guitar. Theses pickups are made by coiling a metal piece of ire around a magnet thousands of times which will then create an electromagnetic field between the pickup and the string allowing the pick up to transmit the sound form the guitar to the amp.

There are three different types of amps and they al have different components the 1st amp is a digital modeling amp which runs off modern day technology to create an amplified sound. The next is a solid-state amp with runs off transistors and other components to amplify the sound. Yet another way to make an amp is by using vales/tubes and these are called valve amps. These run off as vacuum valve(s) to amplify the instment.
