Snow White AutoWah
BJF envelope filter based on 1991 rack design. Lightning-fast tracking, tuned like a real wah pedal.
The Snow White AutoWah is based on a BJF remote wah circuit from a 1991 rack unit, redesigned with envelope controls. The current GB version combines the original Snow White with the Bass version, adding a GTR-BASS switch for instrument-specific voicing.
Five controls: GTR-BASS switch selects guitar or bass mode, Sensitivity sets filter trigger level (adjustable further via guitar volume), Bias controls resonance frequency (works as sweepable filter when Sensitivity is off), Resonance sets filter Q-factor sharpness, and Decay controls how fast the filter returns to rest.
Current draw is 15mA at 9V. Input impedance 500K, output 1K ohms. True bypass switching. Fast Decay settings give wah on every note; slow creates traditional auto-wah sweeps.
