...very tidy factory wiring, strange center terminal thingy where the jack wires connect to the circuit, but the surprise was that the tone caps were tiny ceramic discs. I know that this was common on Fender guitars in the early days but on a Gibson I expected to see something else. Immediately my "should I upgrade" brain kicked in. What is the consensus these days? Would it sound that much different if I put in PIO or orange drops or Mallorys? Incidentally, the reason I finally decided to look inside this guitar which I've owned for two years was in anticipation of changing over to 50s wiring. Since the caps play such an important role with that is why I'm wondering about the upgrade. All opinions welcome!
