Fabulous sounding auto-wah from Mad Professor. It has velcro on the bottom. Conservatively rated in Very Good condition because it has a few very slight surface dings, but really it is in excellent condition. This pedal comes with the box and "box candies".

From the Interwebs:

The New Snow White AutoWah (GB) is a combination of the previous Snow White AutoWah and the Snow White Bass AutoWah pedals. Now both of those fabulous auto wah sounds are in the same pedal making the unit even more versatile. Snow White AutoWah (GB) has a very fast tracking and accuracy rarely found on autowah/envelope filters. With the four knobs you can have a total control of the effect.

SWAW works both with both guitar and bass and you can fine-tune the pedal to suit your instrument, 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.

Product details

CONTROLS:

GTR-BASS-SWITCH: Selects the mode tailored for guitar or bass.

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.
