i've got quite a few high gain amps in my studio, Mesa Dual Recto (2-channel), Peavey 6505, Engl Blackmore, Orange Rockerverb 50, Sansamp PSA1, Mesa Triaxis etc through Mesa OS Recto 4x12/Marshall 1960 cabs (full list at www.facebook.com/inversionstudios )
it's a recording studio, not a jamming studio but drop me a PM and i'm sure we can work something out!
and cheers for the heads up cynanidejunkie I didn't know there was a Soldano dealer here - itching to try out that SLO100!
