Learning how to play B-Bender is easy. Here's how to get started:
Use a guitar strap. To begin you may find it helpful to stand.
Check out how the Bender feels. Push the guitar neck down and you'll feel a satisfying tug on your guitar strap as the B-Bender is actuated. Now stop pushing down on the neck and allow the return spring inside the B-Bender to pull the guitar neck back to the original position. If you are playing a B-Bender that has been properly set up this move feels very smooth and the B-Bender mechanism is totally silent.
Tune as usual and then actuate the B-Bender and tune the note at the end of the bend by turning the thumb wheel located on the backplate.
Play an A chord in the first position but don't finger the B string. Strum the chord and use the B-Bender to pull the B string note up one full step to resolve the A chord.
