Thanks for the new sound file.
I know this sounds dumb, but make sure the cables are plugged into the correct jacks. This mistake happens to me every once in a while because i’m not paying close enough attention when the pedal is flipped upside down. If that’s not the issue, continue…
Plug in amp to the pedal. Make sure the pedal in engaged (not bypassed)… With a metal object, like some tweezers or screw driver, that you are holding (make sure you are holding the metal part of the tool) touch the tip of output jack…you should hear a loud noise from the amp. Then touch pin 6 of U2 (the first TL072 in the signal path). You should hear a similar loud sound from the amp.
Did these two points make the expected noise?
Let me know what you find.
