Description
The GUP Tech Double Donut pairs two independent boost circuits in a single 1590BB enclosure, allowing you to engage the left side, right side, or both simultaneously. Each circuit includes a tone control that shapes midrange response from subtle presence to pronounced mid-cut character. The pedal operates on 9V DC (center negative) with buffered switching and draws 10mA of current.
