Dan,
Thanks for the pictures. A lot of your leads seem really long, you may want to clip them shorter so they have less chance of shorting together. Make sure the the back of the pots aren’t shorting any leads on the board.
Are you able to hear any LFO sound when the pedal is engaged and you turn up your amp loud? If so, is the rate and volume of the LFO adjustable with the controls?
Are those little pieces of solder on the top of the board near R33? If so, clean those up (and any others around the board). Also, resolder R29 and push it closer to the board. If any of the components around that area of the board are touching or shorted out against anything then the muting circuit may be malfunctioning. So check all the solder joints on the components around R29 to make sure nothing is shorted.
Let me know what you find.
