Black Mist - an op-amp based fuzz and sustain, offering a range of overdrive and distortion tones, primarily focused on lower frequencies. Shoegazey and sludgy to be sure, however the clarity control lets you blend in a boosted cleaner tone to cut through a mix.

Inspired by op-amp based Big Muff circuits, Black Mist has gone through 2 years of refinement. High quality WIMA film capacitors and Neutrik audio jacks are used for high-reliability. The power section is flexible, allowing 9V or 18V DC operation, and space is reserved for a 9V battery.
