Okay so I'm about to embark on a little adventure doing something I've never done - namely taking a stock instrument and modding/upgrading it. I'm buying a MIM 5-string Fender Jazz because I've got a line on one for next to nothing and I suffer from GAS in a big way! So in other words, I don't need this bass, but I'm getting it anyway. I've got a Geddy 4-string that I love so right away I know I want to swap the bridge for a Badass or something similar. I've been checking around and can't seem to find a Badass for a 5-string. So first question....bridge recommendations? I'm mostly interested in killer sustain. I don't have any experience with MIM pick-ups....so should I replace whats there? Other upgrades I should consider? Thanks for any advice!
