EarthQuaker Devices sunn O))) Life Pedal Octave Distortion + Booster V3

The sunn O))) Life Pedal V3 may just be the most refined approach for heavy, crushing tone available. Splitting the octave controls out to become independent (vs. previous models), the circuit itself has been updated to allow for a more pronounced octave effect. Alongside precise controls for distortion and boost, you get full tweakability to tame—or let loose—the Life Pedal's aggressive potential.
