From what I'm looking at, Jerry Only uses dual split-coil (P-style) pickups in his basses, that will give you some definite low-end. I recommend not skimping on these (or the bridge); buy premium pickups and bridges for the most tone from the instrument. Having said that, Jerry simply runs his signal full-on from the bass, he hasn't got a volume or tone knob on it at all.
He's running an Acoustic head as a pre-amp into Ampeg SVT amps and cabinets - very easy-to-find stuff, available at most any halfway serious music stores. His strings are Rotosound roundwounds, again very typical and easy to find. I personally play and like DR's Black Beauties, more for the feel than for the looks, although a horror-punk bassist might appreciate having black strings.
Good luck with your project!
