Hey guys.
I've just put together a loophole pedal and everything works like it should. The only problem I have is that I cannot hear my guitar on playback. Has anyone else ran into this problem and fixed it?
You need to audio probe the output of IC1A. Check for output on these locations:
Pin1 of IC1A
Lug3 of the Dry pot.
The junction of C5 and R7.
If you are losing signal at any of those points, that will indicate the problem area. If so, check for any solder bridges on your traces, whether or not the pot is bad and/or problems at the component level (caps, resistors, etc).
