I'm probing this op amp



Pin 3 is a clear signal

Pin 1 however is glitched and horrific, this is the sound i basically get from the other end of the pedal (once it passes thorugh)

What are your pin voltages?

PSA: this was solved, it was a broken 9V power socket. I didn’t pick up on it because it Daisy Seed with fall back on USB power and can still trigger the LEDs even without 9V input, so I had working LEDs but not a working IC
