The Demon is a low to medium-high gain drive with distortion-like capabilities. With the gate/boost mod, it jumps into the gated fuzz range! The Demon can do the “just on the verge of breakup” thing at low drive settings or a pushed amp sound at higher drive settings.

The Demon is in fact the pedal known formerly known as “Oh See Demon.” It was changed to avoid product confusion. The circuit remains the same.
