AMT WH-1 Japanese Girl Wah Wah Pedal w/ 9V Power Supply

The Japanese Girl Wah is an optical version of the classic "WAH-WAH" effect, but with added improvements. Optical control increases the service life of the effect by eliminating the frequent strain and wear on the control potentiometer. The optical sensor also provides for a smoother transition in frequency changes, and eliminates the dreaded "scratchy" potentiometer sound. Found on the left side of the pedal, is a 3-way toggle switch, offering three different wah frequency sweeps that the user can choose from. Each setting will change the vocal range of the wah, it's almost like having three different wah pedals all in one!
