So I have this '74 Jazz bass that I love for it's feel and tone, especially the bridge pickup. But it's thin in the mix and I rarely play it outside of the house because I almost always have trouble hearing myself with this bass either in rehearsal or on gigs. I've tried changing settings on my amp but it just doesn't get me where I need to be sonically. Notwithstanding the nuances of the Jazz bass and how it can be sometimes hard to hear in a mix with a lot of other instruments (and not wanting to get into a P v. J discussion because I'm aware of the differences), I'm wondering whether a rewind of the pickups might mitigate some of the trouble cutting through. Add to that, I just tested a newer Jazz bass at home (2013 MIJ '66 RI) and the output is much stronger. Both basses currently have brand new strings on them. Both set up by me with relatively low action. Do pickups deliver less output over time? Should I first consider having the original pups rewound? I like the tone of the '74 better and I'm wondering whether rewinding the pups will boost the output while more or less maintaining the tone. I know there's a bit of an apples to oranges element to this question because (from what I have read) the 70's pickup spacing can be deliver a "thinner" sound. I've also read that Lindy Fralin can rewind the original pickups to spec for relatively cheap. So I'm wondering if that is the first place to start. Thanks.
