Abstract: A protective device for the rear surface of a guitar, especially an electric guitar, comprising a flat pad of protective material adapted to be removably secured to the rear surface of the guitar to protect areas likely to be scratched by a player's clothing, for example by a belt buckle. In a preferred form the pad comprises a vinyl or leatherlike material with a plurality of elastic loops sized to be secured to existing guitar strap studs on the body of the guitar, or to be looped directly over the upper and lower horns of the typical electric guitar body.
