I've had the same problem with my Agile Les Paul. My treble pickup won't sound unless I hit the string really hard, then it sounds more like the bridge pickup is actually picking up the vibrations. Any suggestions for running continuity test? And by blowing out the switch, do you guys mean just blasting air over it? I can try that, but it seems like the pickup may be dead. I tried running continuity tests from the pots to the switch and all seems fine. I haven't tried from the switch to the pickups though.
