Currently have 4 amps.
Mesa Titan. This is my main rock band gigging amp racked with a Korg tuner going into Mesa 210 and 212 powerhouse cabs.
I also have a mesa big block 750 which I've been trying to sell for a while. Sounds great but the titan is much more versatile having 2 channels.
Fender tbp-1 and QSC PLX 2402 rig which I tend to play through a pair of Markbass 410 cabs. Use this set up mainly with my functions band as it's very clean and has more headroom than I'll ever need.
Finally have a markbass LM2 800 which I use in rehearsal rooms as invariably the practice amps are something really crap like a worn out ashdown. I Also carry his amp to gigs in case my main rig blows up - fits in a handy little shoulder bag.
