I'm going to order some wiring for the myriad of guitars I have to work on, and i'm not sure what kind of wiring is best/needed. There are so many kinds... I will basically just need it for pots, pup switch, and plug. I will want it shielded. I have seen many types, with different amounts of conductors and such... I dont know what any of these specifications mean though, will someone fill me in with everything i need to know?
