This is a Krank Distortus Maximus Distortion Guitar Effect Pedal. The Distortus Maximus packs all the bone-crunching tone of Krank amps into a compact pedal. Easy to operate with 3-band EQ, gain, and master controls. Achieve the high-gain harmonic flavors of the Revolution 1/Krankenstein amps that other distortion effects just can't deliver. It's over-the-top insanity with the warmth and clarity you expect from Krank.
