Many think that electric guitars are basically guitars that require electrical power and an amplifier to play. Perhaps these are true, but these are not all there is to an electric guitar. This piece of instrument converts the vibrations of its strings into electric signals that are then amplified in order to be heard by the audience. But because of its distinct and versatile sound, the electric guitar has figured prominently in many kinds of music, but most especially rock and roll. Guitarists in rock and roll bands are much idolized because they make great sounds.
