Entirely too much fun
Simply a great pedal. I always keep the mini switch in dry mode. It's great in low blend and sustain settings, for adding overtones, or just fraying your tone a little. And of course it can completely fuzz out if that's what you want. It reacts beautifully with my all-tube amp, and if i switch to the drive channel on my head, it makes a throaty crunch that tapers off into the finer distortion of the muff. The sustain knob is also pretty foot-friendly for rolling your gain in a solo. I never use the normal or bass boost modes for bass, but I have run a guitar through it in normal mode and it sounded really good for anything that calls for an ultra-distorted tone. I have read comments by guitarist that say the normal mode does not sound exactly like the classic big muff, but I wouldn't know. Very good buy, sturdy build, good tone, and pedals don't get much cheaper than this.
