Smooth silicon transistor (loosely based on the "Fuzz Face" ) fuzz with a variable input EQ "fatness" to tune in how much bass you like. The variable input EQ helps dial in how the fuzz responds to your picking and the amount of fuzz vs overdrive. Set to the most bass heavy side gets the most fuzz as well as a compressed and slower attack. Set to the thinner side has a fast and more articulate picking attack with clearer definition or dynamics.
Cleans up well with the fuzz knob and has a lot of level on tap for driving an amps input harder.
