Lance, A B-Bender is a device attached to an electric guitar (usually a Telecaster) at the bridge that allows for the "B" string to be bent up and down to give a similar sound to a pedal steel. It involves routing out the back of the guitar, installing the device, and to bend the string, you manipulate the guitar strap button near the neck. I used one once, and while it's great to play with, it takes a lot of practice to use it just right. Mitch Matthews Gravel Train/Sunken Road
