Ok, here is a really dumb question, how do you ground a circuit??? Take one of the pcb's from General Guitar Gadgets, as an example. All the 'ground wires go to the same point on the circuit but what do you do with them from there?

The ground wires from the input and output jacks should connect to the board as well. That's where they go.

Ahh, thanks, I wasn't sure, I've seen some that have a screw through the circuit board and the trace goes back to that, so I was a little confused.

Thats not a dumb question.  If you dont know you shouldnt be afraid to ask--thats what this is for...I try to find out on my own and through the search..if that fails ill ask here...If asking is dumb than you should see my threads... :lol:
