I agree with the guy who said you should go with something entirely different, like a stingray. There's an incredibly huge palette of sounds in a stingray h/s, and if ya really wanna go for broke I'd check out a big al. 3 pickups, 4 band eq, active passive option with an additional tone control for passive, plus the ability to throw the pickups into series or parallel make that bass hard to beat in terms of ground covered. And it's the same price as jazz. Much better quality control with MM too, but I say that in hopes of not opening that can 'o worms.
And for the record, I currently own 4 MMs, 4 Fenders, the custom made monster in the vid below, and 2 warwicks. Have owned 3 other MMs, about 10 other Fenders (MIA and MIM), and 3 other warwicks. Not to mention lots of other basses. None of my other basses came anywhere near the 2 musicians above in terms of versatility.
