The Snow White AutoWah (SWAW) is a pedal that matches both guitar and bass and is tuned like a real wah. The new Snow White AutoWah (GB) combines the previous Snow White AutoWah and Snow White Bass AutoWah pedals, delivering both great wah sounds in one pedal for even more versatility. With lightning-fast tracking and precision rarely found in auto-wah/envelope filters, four knobs give you complete control over the effect. SWAW lets you fine-tune the pedal to suit your instrument, playing style, and tonal preferences for both guitar and bass. It features a unique DECAY control that adjusts the rate at which the filter frequency drops, allowing you to set it for a fast, note-by-note wah effect or a slower, more traditional auto-wah sound. SPECIFICATIONS SENSITIVITY: Adjust the filter trigger level to suit your guitar/bass output and playing touch. You can further change the sensitivity by controlling your guitar's volume knob while you play. BIAS: Adjusts the resonance frequency of the filter. With the SENSITIVITY control fully counterclockwise (OFF), the BIAS control can be used as a sweepable filter. RESONANCE: Adjusts the Q (sharpness) of the filter. DECAY: Adjusts how quickly the filter frequency returns to its rest point. Faster settings give you a per-note wah effect, while slower settings give you a more traditional auto-wah sound. PLAYING: SWAW is a voltage-controlled filter, and the envelope control circuit is designed to follow the dynamics of your guitar/bass, so it may take some time to get used to the controls. Set your guitar volume to 8-10 and try out various playing techniques. GTR / BASS: You can switch between GTR for guitar and BASS for bass to select the position that suits your instrument.
