I just got a MIM Jazz and have two questions about it. 1) I would like to upgrade the bridge with a heavier model. Been looking at the Badass and Badass II, but it appears that the bases of these bridges are thicker than the standard Fender, and the saddles look higher, so string height may be a concern. Has anyone here had issues getting low action with this upgrade? Seems I read that Jeff Berlin once had a P-bass with this bridge and had to sink it 1/8" into the body. Would a heavier standard bridge (like what I might get from Allparts or WD Music) do just as well tonewise? I'm also going to upgrade the pups (the bass is a 1996- both pups hum even when vol balanced), and right now I'm leaning toward true single-coil pups (as opposed to split-coil J-style pups) to keep the traditional Jazz Bass sound. So... how much of a role does the standard Fender bridge play in the J sound? If I simply want to nail the J tone, would I be better off getting a bridge as close to the original as possible? 2) The original owner of my bass had put stickers all over the body. The original Arctic White has darkened in the areas where there were no stickers but not so much where the stickers were placed. It looks okay from 10 feet or so, but inside that, it looks like cream/white patchwork. Anything I can do short of sanding and refinishing the whole body? Thanks in advance.
