The amplifier or amp is an electric unit for electric guitar or bass. There are two parts to an electric guitar: an electronic part for the amplification, and an electro-mechanical one when a speaker changes an electrical signal into an acoustic signal. We can do a lot of things with an amplifier, for example: the echo effect.
There are two types of amplifier: the tube amp which was the first unit with signal amplification, and the transistor amp; the transistor uses less electricity so it is more practical.The amp is a unit which has enough power to make you deaf, so be careful... Now that you know what an amp is, go get your guitar and hit those chords!
