here at Just Pedals we love this Mad Professor Snow White Auto Wah PCB Pedal.
The SNOW WHITE AUTOWAH (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 instru-ment, 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.
Controls
- SENSITIVITY: Sets the filter trigger level, tune this carefully to fit your guitar/bass output and your playing touch. You can further change the sensitivity from your guitar volume knob while playing.
- BIAS: Controls the filter resonance frequency. When Sensitivity is turned fully off the Bias can be used as a sweepable filter.
- RESONANCE: Controls the sharpness or Q-factor of the filter.
- DECAY: Controls how fast the filter frequency falls back to resting point (that is set with the Bias control). This can be set fast (CW) so you get the wah effect on every note or slow for a more traditional auto wah sound.
- PLAYING: Please take time to get used to the controls and as this is a voltage control filter it will react to your playing touch. The envelope control circuit is carefully designed to follow the dynamics of guitar/bass and it might take some time to master the Auto Wah playing technics. Try also adjusting guitar volume between 8 and 10 to further expand use.

Pedal
A pedal is an electronic device that alters the sound of an electric guitar by applying various effects. Pedals are typically connected in a series between the guitar and amplifier, allowing guitarists to switch effects on and off with their feet while playing.
This enables musicians to quickly and easily change their sound, adding versatility and creativity to their performances.
Pedals are essential tools in many musical genres, including rock, blues, jazz, and metal, allowing artists to craft distinctive and dynamic soundscapes.
Once you buy one, you can’t stop and then you have to sell them and buy more.
Wah
A wah pedal, short for “wah-wah” pedal, is an effects pedal commonly used with electric guitars and occasionally with electric keyboards and bass guitars. It’s known for its distinctive sound, characterized by a sweeping, resonant filter effect that mimics the human voice saying “wah.” Here’s how a wah pedal works and some common features:
1. **Pedal Design**: A wah pedal typically consists of a foot-operated pedal and a housing unit. The pedal is attached to a potentiometer (variable resistor) inside the housing, which adjusts the frequency response of the audio signal based on the pedal’s position.
2. **Expression Pedal Compatibility**: Many wah pedals are compatible with expression pedals, allowing players to control the wah effect in real-time using their foot. This adds a dynamic and expressive element to the performance, enabling players to vary the intensity and speed of the wah effect as they play.
3. **Sweep Range**: The sweep range refers to the range of frequencies affected by the wah pedal. As the pedal is rocked back and forth, it sweeps through a range of frequencies, emphasizing certain frequencies while attenuating others. This creates the characteristic “wah” sound.
4. **Q Control**: Some wah pedals feature a Q control, also known as resonance or bandwidth control, which adjusts the width of the frequency band affected by the wah effect. Higher Q settings result in a narrower band of frequencies being emphasized, producing a more pronounced and focused wah sound, while lower Q settings produce a broader, more subtle effect.
5. **True Bypass**: Like many other effects pedals, wah pedals may feature true bypass circuitry to ensure that the pedal does not color or degrade the guitar signal when it’s not in use. True bypass preserves the tone and integrity of the instrument’s sound when the wah effect is bypassed.
6. **LED Indicator**: Some wah pedals include an LED indicator to indicate when the effect is engaged. This provides visual feedback to the player, especially useful in low-light settings or on dimly lit stages.
7. **Treadle Grip**: The treadle grip refers to the surface texture or material of the pedal’s foot surface. Some wah pedals feature textured or ribbed surfaces to provide better grip and control, especially when using the pedal with bare feet or in slippery conditions.
Overall, a wah pedal is a versatile and expressive effect that adds character and flair to guitar solos, rhythm playing, and improvisations. Whether used for funky rhythm parts, expressive lead lines, or experimental sounds, a wah pedal offers guitarists a wide range of creative possibilities for shaping their tone and adding dynamic expression to their playing.
