Zvex Woolly Mammoth
Unknown brand · pedal
The ZVEX Woolly Mammoth is a fuzz pedal built for bass, delivering thick, uncompressed saturation with a dynamic, tube-amp-like response to pick attack rather than a brick-wall wall of fuzz. Its four controls, Output, EQ, Pinch, and Wool, shape the voice in detail: EQ refines the tone in a mix, Pinch alters the character of the overtones from a sharper fuzz to a broken, overdrive-like edge, and Wool adds or removes hair and gristle in the fuzz texture. Played with a lighter touch, it reveals a pretty, dynamic distortion with overtones reminiscent of an electric piano; dug in harder, it turns thick and aggressive. It suits bass players in rock and experimental styles wanting a fuzzy, textured, highly touch-responsive tone rather than a fixed, one-note fuzz voice.
