So first of all whichever bass takes me fancy on the day. So either:
Sire Marcus Miller M3
Squier CV 50s P Bass
Bitsa P Bass
"Bleeding Sunflower" Jazz bass (comes everywhere with me) - look at the build thread
cabled into the pedaltrain:
TC Polytune (must have)
EHX Big Muff Pi
Tone City Golden Plexi - yes, a guitar distortion, used for one song usually.
Boss OC-3
Tone City Angel Wing Chorus - yes, a guitar chorus, used for one or two songs.
(all powered by Stagg plug and daisy chain)
Into Amp and Cab
Fender Rumble 500 (Vintage and contour switches engaged, just a touch of drive dialled in, EQ left nearly flat)
Orange 410 cab
I think that's it.
