Inspired by the ’71 “triangle” and the later “Red Army / Civil War” Muffs, the Red Muck boasts a wider gamut of saturation and varied degrees of compression and sustain on tap. The Boost footswitch engages a dedicated section of the circuit, separately tuned to hit the front end of the Red Muck and generate even fatter walls of Fuzz-Distortion or with the Gain set lower, function as a High-Gain-Stage footswitch.
