Bellows

The Bellows is a two-control fuzz driver that EarthQuaker built to sit between amp-like grit and saturated fuzz without losing bass frequencies in the process. Level adjusts output by modifying the transistor bias voltage — some noise while turning is normal. Drive sweeps input gain from thinner, cleaner breakup counterclockwise to thicker, growling saturation clockwise. Full-range frequency response makes it as comfortable on bass as on guitar. At lower Drive settings it behaves like a pushed amp; wide open it moves into fully saturated fuzz territory. True bypass via relay switching means the audio path needs power to pass signal. 9V DC, 13mA, 2.1mm negative-center barrel. No longer in production.
