I recently finished a Muffin Fuzz, the 75 variant, with the tone bypass switch. I am getting some nice tones, but a first noticed the bypassed setting was way louder than when the tone option was engaged. At first I thought it was an issue with the bypassed setting (I put in a forum post on that), but I realized the issue is in the tone setting (I believe this is the 'standard' muff sound). The overall volume is low. When volume is maxed (and sustain low or maxed), it is louder than unity, but not by much. I expected a lot more volume, like other gain pedals I have built. I feel something is off? Let me know if you have any ideas...
