Ok, so our "PCB" has little holes drilled into each little gold circle I think due to too much pressure put on them by the closer location to the sensor things. So I hope you guys know about what's goin' on, cause I have no clue. Oh and just because this is the newest post, don't disregard the guy's post before me

Ok thanks, cause yeah, I did this fix, and it worked for about a week, then instead of just the yellow button cutting out, now the red, yellow, blue, and orange buttons cut out

So now I'm stuck with a faulty Les Paul, a faulty Xplorer (badly made, whammy bar came off), and a crappy Fender (one of the messed up Rock Band models).
Have not done the fix described int his thread, so Guitar is still standard, but on looking at the connectors in the neck I found that they too have in pin holes drilled in. I think I'm going to attempt to tin the connectors to see if that fixes it.
I noticed the the pins in the main body seem awfuly sharp (like needles). I suspect that this and the neck moving in the joint while being played may be wearing out the connectors in the neck. if this is the case then this is just going to keep happening. (Very poor design in my opinion)
