I just put this together this afternoon and I can't get it to make much noise when the balance knob is turned to fuzz. At first, I had put the Q3 transistor backwards, and it made a fuzzy sound, but very quiet, when the balance was turned all the way to the right. I reversed Q3 to be the correct way, but the fuzz pretty much disappeared and it's still very quiet. I suppose there's a possibility that I damaged it when I removed it and flipped it, but I'm not sure. I've only built a couple of DIY pedal kits before, nothing I've had to source myself, so I'm sure I screwed something up, I just don't have the base knowledge to figure out what. Any help would be appreciated, thank you.
