Jazz basses (one fretted, the other one less so) into an Aphex 1404 optical compressor, then through a DHA VT1 DI/EQ to an SWR SM400 into a Barefaced Compact.
I use this for everything: festivals, club gigs, pubs, recording etc...
I've got a few home-made effects in the chain too for some extra frippery, but mostly it's the top line setup.
