This is the Mad Professor Snow White Auto Wah PCB Pedal from Mad, listed in Guitar Pedals on guitars pedals amps and stuff.. Read More below.

Description

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.

Guitar Pedals

Guitar pedals are compact effects units that shape and enhance a guitar’s sound, sitting between the instrument and the amplifier. They include gain pedals like overdrive and distortion, modulation effects such as chorus and tremolo, time-based effects like delay and reverb, and essential utilities including tuners, compressors and loopers. Understanding basic things such as pedal type, signal order, power requirements and intended use helps players choose pedals that suit their style, setup and playing environment.

Wah

Wah pedals are all about expression. By rocking the foot pedal back and forth, you sweep through frequencies to create that classic vocal-like “wah-wah” sound. From funk to rock solos, the wah adds movement, personality, and attitude to your tone. Think Hendrix, Clapton, or Slash — each used a wah to make their guitar sing. Whether you prefer a classic Cry Baby or a modern auto-wah, this effect remains one of the most recognisable sounds in guitar history.
