I've got this Bill Lawrence l500xl that I've put j to my Les Paul studio. I wired it based on the les Paul wiring diagram, and it worked alright but the volume was all or nothing and the tone didn't work at all. (That's the wiring in the picture) then I tried the pickups wiring diagram and it all works but is extremely quiet. I have to turn my amp up all the way just to hear a little sound. Any ideas?
