My stack seems to change on a pretty regular basis but it's kind of settled into this:
Custom 6-string fretless Alembic
Homemade 6-string fretless with Alembic hardware and electronics
(There are some other basses, but those are the two that I actually play.)
Alesis Powertrip 8 power distribution and rack light
Shure UT14 UHF wireless system
Eden Navigator
TC Electronic M-ONE effects
Ampeg B2R into 1-18 Carvin for the bottom
Mesa Boogie Bass 400+ into Eden 210XLT 4 ohm for the highs
Not shown is a Peterson strobe tuner model R450
