D3lay not affected

When playing guitar through the pedal the mix and level knobs affect the signal, but the others do not. The non-audible pots measurements change when they are rotated. There is no audible oscillation. The FV-1 seems to have normal voltages. Is there a signal path I can probe to solve this wacky mystery? Any perspective is appreciated. I am aware that I need to clean up the soldering and leads. d3lay.jpg
 
You can also access the programs built into the FV-1 by grounding pin13. you can do this by slidering a wire onto whichever side of R5 connects to pin13 and grounding that wire.

This would get you the patches 0, 1, and 2 listed here (depending on toggle switch position).

your aware that all of the pcb's here are designed to have pcb mounted pots right?
There been a definite frequency in the troubleshooting threads lately. Is this a Reddit trend or something? Wire surplus?
Anyway, OP:
Ground the eeprom pin as previously discussed. If it's still no dice/dry only, verify your oscillator is oscillating. Either with a scope or a DMM that will count frequency.
If you have 3.3v, no internal program output and a proper clock, your fv-1 is bad.
If internal programs work, your clock and fv-1 are good but there's an issue with your eeprom.
If nothing works, including your clock, your clock is bad.
 
This is not to be mean, but most of the solder joints look cold and rough and it looks like the board is soaked in flux. The joints on the legs of the fv-1 look very suspect. I would reflow everything and clean the board
