why and when did you decide that? this is for those who play small to medium sized venues with decent PA support. epsecially for those fond of heavier genres & stage volume enthusiasts...at what point did you decide an SVT didn't have enough volume for your needs, and what did you try next? in my case, i've settled on the fact that i need totally unreasonable amounts of volume. i need to be encased in nauseating bass from head to toe and be heard over a full stack and heavy handed drummer. it doesn't help that white light / great annihilator period SWANS is my favorite band. i finally got my SVT-CL back from the shop after some tube issues and the amp sounds better, but still not as loud as i thought it'd be through an 810 and 215 running at 2 ohms. i mean yes, it's loud. but my rig is still not giving me the full body experience i'm looking for. the room acoustics in our practice space are horrible as well. i have great faith in my tech, and he's serviced a fellow doom oriented band i know, so i can only assume my amp has a clean bill of health now with a full matched set of tubes. at this point i have to ask myself if i should add another amp, or what.
