After finishing the Silver Pony 2 build, everything seem to be working on the first go (LEDs, Pots, drive and boost channels)....EXCEPT for the 3 way switch. When set to position 1 (GE), it's more compressed sounding, so I think that is working correctly. The clipping changes when switched from position 1 (GE) however positions 2 (LED) and 3 (SI) sound exactly the same.
I've tried reflowing every joint and also have been playing around with a signal tester to see if there was anything that sounded strange. I noticed some odd, low end sounds coming from the top legs of the 683 cap and the 10k resistor to the right of it. I also noticed some weird sounds on the top legs of the 4 resistors in the bottom left hand corner of the board (10k, 1M). i tried resoldering these joints, no change,
I also desoldered the switch and oriented it in the opposite direction– no change in functionality.
Any thoughts on how to go about troubleshooting this? I've built over a dozen BYOC pedals, and this is one of the more bizarre issues I've encountered considering the circuit otherwise sounds correct (though there could be other things off with it sonically, I am new to Klons/Klones). What I've tried so far is all based on past troubleshooting experience, no real technical knowledge.
Any insights would be appreciated!
