Hi all. I'm soldering a set of Fender Original Vintage Jazz bass pup's to my JB and I don't know what to do with the two included copper shields. I don't even know what's the use for these copper shields. Each one has a wire soldered to it, but I don't know what I should solder these wires to. I have a gig tomorrow and neeed to finish the job tonight necessarily. Thanks in advance!
