I don't consider all my stuff my 'rig'. A least two basses will never see stage time again; The Ripper and the SD Curlee are keepsakes. Some basses are trade-bait. Some are backups. The current rig is kinda weird. There are some amps and cabs that got relegated to my home studio, Some are just waiting till we get more room. But I'm using:
Essence 5
Orion 4
Conklin GT-5
G&L Tribute L-2500
Spector Q5
Lightwave Classica 5
into
Moog MurF-105>
Ch.1>Morley Dual wah> Trace Elliot AH-500x>Avatar 2x10
Ch.2>Akai Deep Impact>Digitech BP-200>Sunn Coliseum Bass 300>X-Audio 2x10(yeah, its cheap but it thumps!)
If needed I add a Mackie M1400 power amp and add to cabs; An Acme Low B2 and an Eden 2x10 wedge and replace the Sunn with an TE AH-300.
The Basson B15b, the Hartke 4.5xl and the QSC RMX 850 are my studio stuff.
