The 432k Rev2 is a high-end distortion/filter box combining a hybrid diode/transistor ladder filter with a clean signal path, which then feeds into a transistor drive stage and op-amp style fuzz. It features CV control of the filter cutoff, a low-cut toggle for guitar use, and a noise/feedback loop for experimental tones. The Rev2 adds a “Sustain” knob and additional gain stage clipping for smoother fuzz, and uses a different set of transistors for a distinct voice.
