n. (context music English) A guitar accessory that enables a player to mechanically bend the B-string up a full tone to C-sharp.
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. Originally designed for the Fender Telecaster, B-Benders are now available to fit many solid body electric guitars, and even acoustic guitars.
