They say:

The Frazz Dazzler is a dual-channel, aggressive fuzz with a wide gain range and a full 3-band equalizer. The Frazz uses a unique circuit topology for extremely high gain even on the low gain channel. The high gain channel offers over-the-top saturation with a built-in noise gate. Both channels make use of a variable regulator for a powerful voltage starve system resulting in a range of sounds from lower headroom/more clipping to glitchy, sub-octave tones. Like all Dr. Scientist pedals, the Frazz Dazzler can be used with guitar, bass, synths, and many other instruments.
