i picked up a fender deluxe series pbass at a little local music store and i'm trying to find some info on it. it's a mexican model with p and j pups and a gold metal pickguard and 3 knobs. all the ones i've seen online have 4 knobs and a gold vinyl pickguard however. it's got some wiring issues and may need new pots, but i only paid 200 bucks for it. any help?
