The SWAH based on the Snow White Auto Wah is an excellent Auto Wah that sounds more like a real Wah than other Auto Wah circuits. We have made a few enhancements to the original circuit and also updated this board to include all four on-board potentiometers, larger off-board wiring pads and brand new design.
