Subdecay Noise Theory
Subdecay · pedal
The Subdecay Noise Theory is a parallel waveshaper fuzz pedal, processing the signal through parallel waveshaping circuitry to create complex, layered fuzz textures beyond a standard single-path fuzz circuit. Reflecting Subdecay's reputation for experimental, characterful boutique effects, it's aimed at players wanting unconventional, texturally rich fuzz tones rather than a classic vintage-style fuzz voicing.
