. . . "B-Bender is a guitar accessory that enables a player to mechanically bend the B-string up a whole tone (two frets) to C-sharp. There are several different designs, but all use levers or pulleys inside or outside the guitar body that are activated by a pull or push of the guitar neck, body, or bridge. The resulting tone sounds much like a pedal steel guitar and contributes a \"country\" feeling."@en .
