Built this up the other day. Having a couple of issues. 1st, when I hit the switch to engage the fuzz, the effect comes on slowly and gradually like I'm turning the volume from "0" to "10". 2nd, the level pot is working like a guitar volume pot in that it "cleans up" when I roll the level down.

i may be wrong but the black battery wire might not be meant to be connected to ground if this is a positive ground circuit. should it not connect to the board itself?

That's what it looked like and there's your problem. Remember in this circuit the ground is positive )the red wire) and the DC power is negative (black). So what you've done is connect circuit's power to the footswitch which is grounding the power supply when it's turned off (also eating your battery the whole time if the input jack has a plug in it). When you turn it back on by hitting the footswitch you're restoring the power and it takes a few seconds or however long. You should connect the black battery lead directly to the pcb where it says 'neg'. And that's the only thing that should be connected to that pad. The ground pads on the pcb are where your pink wires are connected. I think they say 'jack' on them. You don't need both of those wires connected to the jacks as the jacks have a common ground with the enclosure. Remove one and use the second pad for the footswitch ground.

Fucking brilliant! That was the problem and it fixed the weird issue with the volume pot as well! Thanks for the assistance!!
