Oh, my amps/speakers:
3 - 2x12" cabs (2 with E120s and 1 with K120s)
3 - McIntosh power amps (2 MC100s and 1 MC2300)
3 - preamps/amps (1 Fender Twin Reverb combo, 1 Fender Pro (in a head cab), 1 SMS Classic)
Lately I've been using the Fender Pro head, a 2x12 E120 cab and a MC100 for gigs and rehearsal. Yes, they all sound a bit different too.

SMS->MC100-> JBL e120 2x12 (use 95% of time)
Mosvalve rt2500 head from a combo 2x12 (hybrid) never use. great blues crunch.
Hot Rod Deluxe3 with K120 (1x12 combo) (use 5% of time)
Twin RI 65 with Waldo Mods as a combo with commonwealths. Just plain butter this one is. I have tried my Commonwealths with all the above and they sound awesome in any of the above too! and rarely use it.
and I have an MC250 and MC50 depending on, well I haven't really used those two lately. I have a 1x12 cab with an E120, and a 2x10 with k-110's. Damn now that I've written it out, that's a lot of stuff Im not using very often.
