The Snow White Auto Wah by Mad Professor is a premium quality auto wah pedal suitable for both guitar and bass. It is based on a 1991 BJF rack mount remote wah circuit and is tuned like a real wah, offering fast tracking and high accuracy rarely found on auto wahs/envelope filters. The pedal has the following technical specifications:
- Supply voltage: 9VDC
- Current consumption: 15mA at 9VDC
- Input impedance: 500K Ohms
- Output impedance: 1K Ohms
- Max input: -20dBV
- Complete bypass (true bypass)
The pedal features four control knobs for total control of the effect:
1. Sensitivity: Sets the filter trigger level, allowing for careful tuning to
fit the guitar/bass output and playing touch.
2. Bias: Controls the filter resonance frequency. When Sensitivity is turned
fully off, Bias can be used as a sweepable filter.
3. Resonance: Controls the sharpness or Q-factor of the filter.
4. Decay: Controls the speed at which the filter frequency falls back to the
resting point, offering the flexibility to set it fast for wah effects on
every note or slower for a more traditional auto wah sound.
The Snow White Auto Wah is hand-made in Finland using premium components, ensuring years of trouble-free operation with superb musical tone. It offers a unique decay control for the filter frequency fall speed, allowing users to fine-tune the pedal to suit their instrument, playing style, and taste of tone.
