Hi Guys, I’ve been pouring over this pedal for a few days now and I must be blind to my error. The pedal works correctly when stitched on but there is no signal at all when the pedal is switched off. Hopefully I’ve just put a wire in the wrong place but I’m stumped! Thanks in advance for any help!!

Let me make sure that I understand you correctly. You're saying that when the footswitch is in the engaged position, the LED lights and overdriven signal is produced by the pedal, which responds properly to the volume, drive and tone controls? But when you switch to bypassed mode, you get no audible output?

Hey sorry for the delayed response, yes that is exactly the situation. I have it plugged in and when the switch is depressed the light comes on and all three knobs seem to work correctly. Then when it’s switched off there is no signal to the amp at all.

That's actually very good news, because it eliminates pretty much every possible defect except for two. So check these two things:

• Check the solder joints at either end of the jumper between lugs 4 & 9 of the footswitch. If either end has a bad solder joint that not making contact, signal won't pass through the jumper as it needs to in bypassed mode.
• The footswitch itself could be bad, specifically not making the required internal contact between lugs 8 and 9 in bypassed mode. This is easily checked using the continuity test mode of a multimeter and testing between those two lugs with the switch in bypassed mode.

Try checking these two things and report back here with your findings.
