Subdecay Octasynth

Subdecay Octasynth – Analog Synth-Style Octave Fuzz Filter

The Subdecay Octasynth is not just an octave pedal — it's a true analog synth engine designed for guitar. Blending aggressive fuzz, sub-octave generation, and envelope-controlled filtering, it transforms your guitar or bass into a gritty, robotic synth monster. From gnarly sub-bass grooves to glitchy filter sweeps and laser-like stabs, the Octasynth delivers unpredictable, raw sonic destruction.

Perfect for players looking to break free from traditional tones, the Octasynth is chaotic, expressive, and alive — with no tracking latency and no digital processing.
