Ok, here goes. Its probably been asked. I have a 5 string jazz bass with passive junker p'ups in it. What do i need to do to update. Seymour duncan. I noticed something like you cant retrofit the active SD jazz's into it or something. Im clueless. Make some suggestions.....bart's EMGs, what would be best?
You oughta' get a good "machinist's" rule (real accurate) and check the string spacing and dimensions of your current pickups. Stew Mac has one for ~$10. Usually, bridge and neck J pups are slightly different sized. Sometimes (to save $ ), manufacturers use same-sized J pickups. Early MIM Fenders an example. If your pickups are different, one option might be the Seymour Duncan 67/70 or 70/74 single coils. `Sposed to deliver the "`62 vibe". The numbers refer to the string spacing...B to G, centerline to centerline. Either set runs ~$123 at discount guitarparts. A little more at Warmoth.
