An electric guitar is an instrument that requires external amplification in order to be heard at typical performance volumes. It uses one or more pickups to convert the vibration of its strings into electrical signals, which ultimately are reproduced as sound by loudspeakers. It was invented in 1932 but didn’t become popular until the 1950s and 1960s. Since then it has evolved into an instrument that is capable of a multitude of sounds and styles in various genres.
