I tried my UL112 with my schroe 1212R stacked run with my carvin bx1200 at a gig I just got home from. All I can say is whoa! Until my UL110 arrives I'll keep stacking my two larger cabs together. So basically I was running a 3-12 stack. That Carvin BX1200 is part of the reason this rig sounded so great. It has MAJOR balls! Even using the regular bass eq pot I couldnt cut enough low-end out. I had to set the graphic eq as an upside-down 'smiley face' (another words frown) in order to cut enough bass eq. Still sounded super bassy and full. Amazing given the way I had the graphic eq set. I never had the master vol on the bx1200 past 3 (bridged @ 4 ohms to give 1200w). I had the schroe 1212r vertical and the UL112 stacked on top vertical as well. I could sure hear myself tonight! Cab stacking will always be my first choice from now on! This setup is actually WAY more power than I need. I wanted to run a stack setup and the only way to do it was to combine the 1212R and the UL112 as thats the only cabs I currently own until my UL110 arrives. The UL112 + 1212R stack was actually too bassy. I would rather not have to cut that much bass... though I'd rather cut it, than have to add it. I should mention that we were playing in a small pub with all wooden floors, and wooden stage. I love playing on that stage, though its too small. Barely fit a three piece on it. I think those that 'mix and match' cabs may be onto something. All I know is that Epi UL112 + schroe 1212R + Carvin BX1200 is magical! Okay, enough rambling from me.
