When I was playing metal, I mostly used an Ibanez SR800 and an Ibanez EDC700 (to a lesser extent I also used a P bass, but since that's out.....) They both had the same 24 fret neck that was thin and fast, and both were active. The SR800 had a P+J setup and the EDC700 had a pair of soapbars. Volume, blend, bass, treble, and sweepable mids for the controls for both. The EDC700 looked really slick and I preferred it's tone over the SR800. Both can be had for a reasonable price used.
And, I second BazzTard's recommendation, both of my Jazz basses with Rotosounds and some overdrive absolutely crush in a metal setting.
