Hi- recently bought a '66 jazz bass. refinished, with a newer, vintage style bridge (how could i afford it otherwise...?). the body and neck are original and that's what i really cared for- the wood. now i opend the PUPS. they look very old. they had this foamy padding material glued to the bottom. i easily took it off. there is nothing written on 'em, unless the remainings of the foam make it unreadable. in any case one of them has the original copper color wound wire, but the bridge PUP has a blue metalic kinnda wire color for the winding wire material. What is THAT? can anyone help in identifying both pups? if i want to restore the instrument as close to a '66 sound, which PUPS do you suggest to put in there for max authenticity of sound? option 1. N.O.S sound(as if NOW was '66) option 2. ones that might have the sound of 40 yo used ones. i just LOVE the sound of old underdog fenders and want to stay away from flashy modern sounding PUPS that have big volume but small...you know what... thanks for your help, Rea.
