Prometheus 3

Dual analog filters inspired by the Korg MS-20 monophonic synthesizer, controlled separately like the MS-20's dual-filter architecture. Both filters can self-oscillate for acidic inharmonic tones with integrated noise gate.

Three parameter knobs with functions mapped per preset. For envelope modes: envelope slope, filter resting point, resonance. For LFO modes: modulation depth, filter cutoff, resonance. Select knob for preset/mode selection. 121 factory presets plus 11 user presets.

Subdecay's most advanced filter pedal with 40 editable parameters including 3 LFOs, envelope shapes, overdrive, tremolo, and LED color. Pixelated envelope modes create sample/hold filter shaped by pick attack. Self-oscillating dual filters with noise gate allow aggressive acid-style filter sounds.
