Complete system with B-Bender, D-Tuner and Palm Lever. The B-Bender bends the string accurately to a C sharp with a slight hip movement against a closely attached lever (which is mounted on the strap button). The D-Tuner gives a Drop-D with one hand movement. The Palm Lever brings the G-string quickly and easily to an A. The basic model comes only with a B-Bender, but can be expanded with the above mentioned components. Includes installation instructions and all needed parts.
