Description
The Snow White Auto Wah traces its DNA back to a 1991 BJF rack-mount remote wah circuit, reworked into a compact envelope filter that actually tracks like a real wah pedal — a rare feat in this category. Where many auto wahs feel sluggish or unpredictable, this one responds fast and accurately to picking dynamics, making it feel more like an expressive filter sweep than a fixed effect.
- Four knobs give you full command over the effect’s shape and intensity
- Works equally well with guitar or bass, so you can dial in tone to match your instrument
- A dedicated decay control sets the filter’s frequency fall-off speed
- Set decay fast for a wah-like snap on every note, or slow it down for a smoother, traditional auto-wah swell
On the board, this pedal sits comfortably in the same slot you’d reserve for a wah — early in the chain, ahead of gain and modulation, where it can react cleanly to your playing dynamics. Bass players get the same tracking precision, letting the filter follow low-end attack without turning muddy.
Like every pedal in the Mad Professor lineup, the Snow White Auto Wah is hand assembled in Finland with premium components, built for long-term reliability and a musical, organic tone rather than a harsh digital sweep.
