This pedal is based on the Green Russian Muff* - a bunch of great features have been added - the main one is the BLEND knob that makes this pedal suitable for bass without using low end. Further internal controls allow you to adjust your sound to your specific needs. The Mammut Muff was developped for Mammut (The Loranes).
