The Snow White AutoWah makes it possible to get a high-quality autowah sound quality for both bass and guitar.
The pedal has very fast response and accuracy, which is not often seen with autowah/envelope filters. The four knobs give you full control over your sound, including sensitivity, resonance, bias and decay.
A decay control is not common on an autowah and allows you to change the rate of frequency decay. The high-quality construction and dynamics make this a very interesting pedal of its kind."
