Glen Burton Gold Electric Guitar, hand signed on the pickguard in silver paint pen by Les Paul (D 2009). Les Paul was an American jazz, country, and blues guitarist, songwriter, luthier, and inventor. He was one of the pioneers of the solid-body electric guitar, which made the sound of rock and roll possible. Paul taught himself how to play guitar and while he is mainly known for jazz and popular music, he had an early career in country music. He is credited with many recording innovations. Although he was not the first to use the technique, his early experiments with overdubbing (also known as sound on sound), delay effects such as tape delay, phasing effects and multitrack recording were among the first to attract widespread attention.
