I have a nashville tele with three single coils in it and the 5 way switch. I also added a push pull pot in the tone knob. I installed a noiseless strat pickup in the center and all of the pickups sound great accept when i active the bridge and center pups together. Then it loses its presence and sounds very distant and not like a song the guitar should make. The center pickup install was a breeze because the one that came out and went in were just two wires. Wondering if the 5 way switch needs replacing? Thanks for your input.
