New version with revised switches now in stock.

Maxon has married the coolest aspects of auto-wah and swept filter effects in this modern addition to their respected 9 Series. Opto-coupler circuitry produces the shimmering, watery filtering effects of vintage units. Threshold and peak sliders control the degree of effect while range and drive switches determine the range and direction of filter sweeps. 3 selectable filter types--Lo Pass, Band Pass, and Hi Pass--plus a frequency range of 100Hz-4kHz produce staggering effects with virtually any instrument or input signal. Features true bypass, die-cast zinc case, and 3-year warranty.
