An
electric guitar uses what are known as pickups which convert the vibration of its steel or nickel strings into an electrical current. This is then made louder with an electric amplifier and a speaker or speakers. The electronic signal that comes from the guitar is sometimes altered with guitar effects ranging from distortion to delay. Most electric guitars have six strings. One of the first solid body electric guitars was invented by Les Paul, a popular model of electric guitar even today although a little different than the original!.
