Sounds like you have a cold solder joint or ground problem. Re-flow everything including off board connections and recheck all common grounding. Also check your cables and only test the pedal by itself with known perfect cables.

If you cannot find it you will need clear photos and voltages:

Source voltage and both chips is what is required.

Google the datasheet to get the pin number and list it so we can tell which reading is what by pin.

IC chips are always listed in order by number following this U shape. Again google datasheet.
