One of the G&L models with the MFD Humbuckers - either the L-2500 or the M-2500. The L-2500 is (IMO) the more versatile of the two, and can provide a reasonable emulation of many popular basses if you are willing to take the time to dial it in correctly. You can get reasonable facsimiles of a P, J, MM and other well-known sounds. The L-2500 will cut through even the most brutal of mixes. The control set on the L-2500 is somewhat unconventional, as the bass and treble controls are "cut only" and you really need to learn the switches to take full advantage of the capabilities of the instrument. One of the switches will put the bass in passive mode, a great solution if your battery happens to check out, and you don't have a replacement. Simply throw the switch and keep playing. If you go with a L-2500, I would suggest that you order one from the factory and request that it be built with the "K option". This option replaces the series/parallel 2-way switch with a 3-way series/parallel/single coil switch. The single-coil option takes one of the most versatile basses available and gives it a nearly ridiculous range of possibilities.
If you prefer a bass with a more "traditional" control set, the M-2500 features the familiar Volume-Blend-Bass-Middle-Treble controls with no switches. The pickups on the M-2500 are essentially the L-2500 PU under-wound by 11%. The M-2500 is often described as more "polite" sounding than the L-2500, but you can still get a very aggressive sound if you wish. It will not offer you quite the same level of angry "snarl" that you can get with a L-2500, but still has enough "oomph" to cut through the mix.
On either model, you get the G&L build quality, which is (IMO) among the best in the price range.
