Distortion and notch filters

SOUND DESTRUCTION DEVICE V3 (Standard Version, pearl)

Total Sonic Destruction, Filter, and Oscillation

Total sonic destruction tool for guitar, or anything with a 1/4″ jack you want to plug into it. It distorts, filters, oscillates, glitches, clips, and does things to your instrument that naturally should not happen. From super thick fuzz, to starved splatty sounds, to wild oscillation that can be controlled with an expression pedal, the Sound Destruction Device sounds like nothing you’ve ever heard.
