Finished...LED works, no sound
« on: December 13, 2009, 02:47:54 PM »
Hi so I finished the pedal a little while ago. I hooked it up and the LED turned on. Then I turned on my amp and there was no sound when bypassed. I turned on the pedal and there was still no sound. All my other pedals worked and the cables worked. Can anyone tell me how I should go about figuring out whats wrong? I have a DMM but I don't know how to use it. Thanks

OK, so I was looking it over and saw a wire on the back of the board that broke from the solder joint and fixed it. Still nothing. So i go back and there's two solder joints on the input/output jacks that came loose, probably when I tried tightening the jacks. I fixed those and now I get sound when bypassed and engaged except the pedal has no effect on my tone when its engaged.

It's most likely a wiring mistake on the board. Check your voltages and wiring.
