Build Your Own Clone Message Board

My mouse works fine in bypass mode but when I switch it on everything has to be dimed to hear anything. If I turn the volume or distortion knob down at all there is no sound. I checked the forum and someone suggested to someone else with the same problem it was a bad footswitch.
Anyway, I checked the resistance on the switch with a multimeter and when the effect is on the resistance between pins 7 and 9 is around 1Meg ohm. Shouldn't this be an open circuit?
So does this mean that my switch is bad?

Thanks in advance for any help.

There should always be infinite resistance between lugs 7 & 9 since they are the throws for lug 8 which is the pole. If you had measured zero resistance across those two lugs there would definitely be something wrong with the switch. Post some up close, in focus and detailed photos of your build. Include shots of both sides of the PCB as well as shots of the wiring to and from the pots, jacks and switch. Don't bother posting blurry photos because they are of no use if details can't be seen.

I'm afraid I don't have a camara that will take a detailed enough photo. Could someone else measure their mouse across pins 7 and 9 (with the effect on) and tell me if they get around 1 meg ohm resistance across them. It is an open circuit in bypass.

Well I finally got around to trying to debug this thing. I can't say how useful the signal tracer is. After 8 months on the shelf it took me about 20 minutes to get this thing working. I just followed the signal path until I had found where it dropped out. Turns out it was just a bad soldering job on the volume pot.

Bottom line, make yourself a signal tracer.
