I agree with Barry.  The signal probe quickly narrowed down to the area of concern.

I think you soldering joints all look great including the ones on the foot switch.  Therefore, I suspect that you have a defective foot switch since it also acts weird when you step on it.  Since you loose signal precisely at the foot switch between lugs 2 and 1 and the solder joints there look fine, I think that is the problem.
