In order to bring you a wah pedal that will last for years, AMT Electronics create the WH-1 Japanese Girl Optical Wah. With optical control, you don't have to worry about the wear and tear done to your control potentiometer, so you can wah just as much as you want. The WH-1 comes with a switchable bandpass via a three-way toggle switch at 0.2-1kHz, 0.3-1.5kHz, and 0.4-2kHz, and its small size guarantees that it will fit on any pedalboard.
