I'm not sure what's the issue. There's a noisy oscillating buzz. I thought it was the opamps and when I removed them I still had the pedal on, but it then produced the effect just very low volume. Thoughts?
No I clipped it out of the case, I've been trouble shooting it my little test jig. I've tried the basic troubleshooting and the op amps are tested in the correct position.
Clean the Back of the Board with some Quality Electronic Cleaner and Toothbrush.
That one in the Blue circle looks contaminated.
Spray away from the Potentiometers!
Looking at the picture I thought the same thing. I re hit it with some solder. No luck. Now it's just super distorted. I feel like progress is being made.

If you don't have Copper Braid, Strip some plain strand copper wire& flatten it.
Make sure you Solder tip is Clean & Tinned, Put the flattened wire it on the joint & lay the Solder tip on it, It should absorb & remove the excess solder.
I take the tip out after nearly every Build & Refresh it.
Put in a Hand Drill or Drill Press & file or sand to a sharp tapered point.
Put back In Soldering Iron & get up to temp & keep putting Solder with flux core on Tip until it sweats.
Turn Soldering Iron until whole tip is Tinned and shiny.
Wipe off excess with damp Sponge.
When Soldering PCB's , Make sure you keep wiping Iron of excess solder & any residue with damp Sponge.
Your finished joint should always look Even & Shiny.
