Right now I'm using the Rolls RP93 to switch between the 3 preamps (Mesa Studio, Mesa Rec Pre, and Soldano SP77), using a Lexicon MPX-G2 for effects, and running dual power amps (Randall RT2/50 for dry tones, Mesa 20/20 for wet), feeding a couple Randall 2x12 and 4x12 cabs. Lotsa good old school gear there. Now I'm just waiting for the rack to show up...
