The B-Bender was invented in 1968 by musicians Gene Parsons and Clarence White of Nashville West and The Byrds. The device was originally called the Parsons/White Pull-String, later renamed the StringBender, and is now best known as the B-Bender. Early prototypes developed by Parsons (a machinist as well as a drummer) included multiple bending devices for the E, B, G and D strings, but guitarist White decided he preferred a single B string bender in the final design. The B string is bent up a full tone by pulling the guitar neck down. This puts pressure on the strap, which is attached to a spring-loaded lever at the base of the neck. The lever arm passes through the body of the guitar and is connected to the B string behind the bridge (Figure A). White's 1956 Telecaster with the original Pull-String is now owned and regularly played by Marty Stuart, who bought it from White's widow.
