Subdecay Variac
Subdecay · pedal
The Subdecay Variac is a boutique voltage-starvation pedal that simulates the effect of running an effects circuit on a depleted battery. Starving the supply voltage produces a sagging, compressed, gated response in which notes bloom unevenly and decay abruptly, with a thin, spitty, lo-fi character rather than a smooth overdrive. The degree of starvation is adjustable, moving from a mildly compressed, spongy feel through to heavily gated, stuttering breakup. It suits lo-fi, experimental and vintage-inspired playing where instability is the desired effect.
