This looks like the post about the switch.... "The switch has a plastic shaft in the center. When you operate it, it opens and closes metal flaps/plates on either side that the wires are attached to. This makes/breaks contact with the pickups. The switch sits in a somewhat narrow slot. It looks like if it's not lined up straight with the slot it can prevent the metal from pushing open. And if the round nut loosens up, it's possible that the switch could turn when you work it. The switch needs to be lined up with the slot and then the round nut tightened. Anyways, I made sure no wires were touching, gave it a shot of contact cleaner, and so far - so good. It hasn't cut out, lost volume, or given me any other problems, and I've worked it quite a bit. Hope it stays that way. Hard to describe. I hope that made sense. I'm attaching some pictures that may help. The solder work was better than I was expecting, but there was a lot of rough wood in the routed areas, and some loose wood chips on the bottom that I vacuumed out. Edit - maybe there was a small piece of wood or sawdust in the switch - IDK. So I guess he's saying that it could be the switch came loose and rotated a bit which caused the mechanism to rub against the side of some slot it sits in, is that right?" ...I haven't had time to play mine today but I'll report back if my switch is acting weird again.
