Hey everyone, I'm doing my own independent research on this stuff and trying to gather information, but I figured I'd put an inquiry out there to the crowd and see what comes back as well. I have an early/mid 90s Carvin LB76 6 string (fretted). It's got a quilted maple top and ebony board. I'm not 100% sure on the body, I think it's maple too. I bought it not quite 3 years ago. It was basically pristine, and still is. The ebony FB is from when you could still get just straight BLACK ebony, and the original owner wisely got it with no inlays or even a headstock logo (and just a glossy natural finish). I've gotten the string gauge and setup where I like them, but I'm still not thrilled with the sound. With EQ-ing I can get some great stuff out of it, and the 50/50 tone of the 2 J style pickups (Carvin H50Ns) is nice, but the individual pickups don't give me what I want by themselves. I use the bridge reasonably often, but almost never the neck. It's kind "neutral" bordering on brittle I guess. So getting the sound more how I like it takes some EQ massaging, especially of the mids and highs. So as near as I can tell, the bass uses 2 Jazz bridge sized pickups, both about 3 3/4" long. The bass has a 9V 2 band active preamp. For amplification, I use either my Genz ShuttleMax 9.2 (or sometimes my GBE 750) or Trace AH 600-12. Both of these are hybrid heads with tube preamps which can get some nice overdriven sounds, and that is definitely something I need to have. My main cabs are a pair of Genz Uber Quads (12 with 2 8s and a tweeter in each one), SWR Goliath III 4x10, Genz 410T XB, and Genz STL 210T. Style-wise and tone-wise I'm all over the map. I like everything from Marcus Miller to John Pattitucci to Stanley to Jaco to Squire, Geezer, Geddy, Justin Chancellor, etc... So I want to be able to do funky, jazzy, heavy, and vintage more or less (not all at the same time necessarily). I love Ken Smiths, Alembics, and Modulus, but I also love a good Japanese P copy from the 70s/80s, etc... So what I'm looking for is a set of great pickups that will be drop in replacements for my bass, and a 2 band preamp that can run on 9 volts (the current battery just sits in the control cavity, not interested in any routing for 1 or 2 battery compartments in the back). I don't really like a ton of low mids in my sound, because it gets too congested and muddy sounding, so a little scoop is fine, but I don't want Fieldy either. I want a platform that I can convincingly reach out to a bunch of different touchstone tones. They don't have to be exact (honestly, I can already get passable Squire type stuff with my current setup). "Good enough for the best cover band in the region" would be cool. Super bonus if the preamp has a push pull for a passive tone. I rarely use the active EQ I have now (mostly the treble), so if someone wants to sell me on making it a fully passive bass, that's fine too (I guess I would just do volume/blend/tone/tone in that case). Mainly overall I want a "sweeter" high end/upper mids, and overall big and punchy and full and defined. I love the MusicMan sound and if I had to pick a single bass sound forever, that would be one of the finalists for sure. So yeah, TL, DR: Set of jazz (bridge) sized pickups, leaning towards stacked humbuckers. 3.75" wide or thereabouts for both (once I get candidates I can call up companies and confirm what I need and eliminate stuff that won't fit precisely). Side tabs, not end tabs. 2 band preamp, volume/blend/bass/treble. Bonus points for push pull passive tone as well (or at least a push pull to go to passive "wide open"). Target budget, maybe $400 or less? Is that doable? Could maybe go up to $500 if I was getting something I was really happy with. For instance the Bartolini 69J1 L/LN set is $230, and the Aguilar OBP 2 is $140, and I think I'd have a good chance of being perfectly happy with those, and in the absence of better information that might be what I end up doing. $500 starts to approach a sort of ridiculous proportion of what I paid for the bass in the first place, so I'm reluctant to dump a bunch of money into it that I would almost certainly never get back. But, if it's going to bring the sound of the bass up to par with how it looks and feels to the extent I would be likely to keep the bass forever, I wouldn't worry too much about the exact dollar figure in terms of "investment". It's more about "budget" I guess. I could also try the newer Carvin/Kiesel H50A pickups which have apparently been revoiced. And they're 70 bucks each, which is certainly tempting, so if anyone has experiences with those I'd love to hear them. I'm not looking to buy right this minute, but hopefully later this year. Hopefully that's not too much information, but I wanted to try to cover the basic questions people are likely to ask. Thanks!
