Electric Guitar

An electric guitar converts string vibrations into electrical impulses via pickups, typically made of metal. The most common type is magnetic, using electromagnetic induction. Electric guitar signals are too weak for loudspeakers, so they're amplified through a guitar amp before being played through a speaker. Electronic circuits can modify the signal to enhance or change the sound. Common effects include reverb, distortion, and overdrive, which is crucial in blues and rock music.
