The electric guitar is a plucked string instrument. The inventor is George Beecham and Adolf Rickenbacker.
Unlike traditional guitars, the principle of sound production is not based on the vibration of the box, but on the principle of electromagnetism. Its body is solid wood, not an empty speaker. The piano is fitted with a coil. They are called pickups. When a magnetized guitar string vibrates, it causes a change in the magnetic flux of the coil on the pickup to produce currents of different frequencies in the coil. When these currents are restored through an electronic speaker, they become the sound of an electric guitar.
