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.

Wah Pedals

Wah pedals use a foot-controlled filter to sweep through frequencies, creating the vocal-like sound heard in funk, rock, soul, metal and psychedelic guitar playing. They can be used rhythmically, expressively or as a fixed tone-shaping filter.

A wah pedal gives the player direct physical control over the effect, making it feel highly responsive and personal. It can make lead lines sing, rhythm parts talk and heavy riffs cut through with extra attitude.

Wah

Wah pedals and related effects are commonly used by guitarists looking to shape their tone in a more focused and creative way. Different designs offer their own response, feel and tonal character depending on the style of music and the type of amplifier or guitar being used.

Many players build pedalboards gradually over time, combining different effects and utilities to create a setup that suits their own sound and workflow. Wah related gear can play an important role in both live performance and studio recording.
