I have a Gibson Les Paul Studio, and I've had it for about 8 months. Recently though, whenever I switch to my bridge pickup, I get no sound through the amp. The other pick-up sounds fine, and then I'll go to the bridge, and start playing, and I'll get like half-second bursts of sound, and lots of silence, then finally itll work fine, until i go to my neck pick-up and come back. Anyone know whats goin on?
