I'd have a custom rig.
1) Solid state/valve two input preamp with stereo effects loop, 4 band parametric eq, stereo line in and dual band compressor featuring
valve side: design based on Alembic preamp
solid state: design based on Radial Bassbone DI
2) Stereo valve power amp 2x400w based on Burman PA design (and a 1 unit Class D PA amp, but it wouldn't need to be custom)
3) two 1x15" + 1x6.5" + HF horn lightweight wedges with neo speakers (capable of being stacked vertically for larger stages)
Basses:
Steinberger graphite necked 5 string headless with chambered mahogany body and custom MM/split coil pickups, Noll 3 band buffered parametric eq.
Steinberger graphite necked 5 string headless, fretless, with chambered mahogany body and custom MM/split coil pickups, Noll 3 band buffered parametric eq.
