I’ve posted this in general but am not sure how to delete the post so I can put it here.
Oh where do I start !!! I’ve build several of these without hiccup, really easy build - until this one. The pedal was exhibiting a super low volume and then nothing. I ran my probe and all was good until till the output of Q3. I figured that it must of been a dud transistor. I cut the bugger off and tacked on the underside of the board and hey presto - it did what that pedal is supposed to do. Roll forward a few days and it’s exhibiting the very same issue again, all good until Q3 gets involved and messes it all up.
Is it possible something is killing Q3 ? I’m really tempted to run a jumper from the base of Q3 to R14 to bypass the bastard all together but I would sooner work out the gremlin.
Any advise would be really appreciated.
