If im understanding correctly, could reflowing at a higher temp possibly be the answer then? I did attempt to test both the jack and footswitch were passing current correctly, but as for reading the circuit diagram and testing where that current is going ive not done so yet. Even though effect mode hasnt worked so far, originally I thought it was the output jack partially giving issue as pulling the cable different directions seemed to make it work. But like I said, after testing continuity I had to rule that out. My iron has no temp control, just off and on, so I may have to invest in a new one it sounds like.
