Snow White Auto-Wah Pedal


BJF designed Auto Wah/ Voltage Control Filter that brings rack mount remote wah to a compact pedal.

PCB Version of the famous Hand-made Auto-Wah.

The Snow White Auto Wah (SWAW) circuit is based on a 1991 BJF rack mount remote wah circuit and is tuned like a real wah. The circuit was redesigned with envelope controls and built into small size pedal.

It has very fast tracking and accuracy rarely found on auto wahs/ envelope filters. With the four knobs you can have total control of the effect. SWAW works both with guitar and bass and you can fine-tune the pedal to suit your instrument, your playing style and your taste of tone. The pedal has a unique decay control for the filter frequency fall speed. You can set it to be fast for wah effects on every note, or slower for a more traditional auto wah sound.
