This thing rules. Got this guys a few years ago and have been a Fuzzrocious fan ever since. I can use it to get a crunchy boost or crank it to get an explosive glitchy fuzz. Sounds amazing with bass through my ampeg tube heads and equally awesome with guitar through my solid state roland jc 120. Highly recommended. The gated boost on this thing is sick. I like to put another overdrive like an EQD Arrows or Fuzzrocious Ram the Man Parts in front of the Demon king to get a glitchy synth type fuzz. I always get compliments on my tone when i use this thing. Great pedal and great company.
