I tend to change things around a lot, but the basic rig is:
'67 Starfire with Alembic Series II pickups/electronics/hardware->Alembic IN-2->Alembic F-2B (trying to get my SF-2 into the signal chain, but having weird noise problems)-> Crest Prolite 3.0-> Mike Arnopol Soundworks 210 Flex.
The cabinet is the most obscure part of the rig and it's amazing. Super high fidelity, reasonably light, and seemingly bullet proof (I've blown up every cabinet I've played at least once, except this one). For a 2x10, it can fill large stages, including outdoors. My drummer nicknamed it "Thor". Here's a review: http://epublish.panaprint.com/article/M ... ticle.html
I just got a Quilter Bass Block 800 for a some shows I'll be flying to. So far it seems pretty cool, but I won't have a chance to try it on a gig for another week. I might pair it with a Grace Design Felix for more comprehensive EQ and a more conventional DI. Or I might just bring along an F-1X, but that's bigger and heavier.
Other gear that gets used are a Sarno CTP, which sounds amazing, I like it better than the F-2B, but it's only mono, an F-1X, and various cabs with K140s. I also have an Eden WXT500 and a Navigator preamp. I find them flexible, but frustrating to get a good solid sound, whereas the Alembics and Sarno sound good no matter how you set them.
Other basses are an early 80s Modulus neck-through 6 string and a '68 Gibson EB-3 with Dark Star pickups, as well as various others not used for these gigs including an amazing David King fretless 5, Modulus Q6, and a custom 5 neck-through that I used for a long time playing funk.
