Check the listing for details. DEATH BY AUDIO Germanium Filter Effects Pedal Gold and Black. Condition: New. Listed at 225.00 USD. The Death By Audio Germanium Filter effects pedal starts with a console-style drive circuit, adds a dash of old-school germanium transistors, then finishes off with an intense DBA-style filter to deliver crushingly heavy, razor sharp sound. The Filter control takes you from bottomless, subwoofered-out lows to searing and brittle highs, with a wealth of tone in between. The Gain knob starts with a dirty boost that spans through saturated drive, spitting distortion and blistering fuzz. Designed to help you find the sweet spot for your instrument in any environment, the Germanium Fuzz is all the power of a recording engineer and studio in one unstoppable pedal.
