Well, that's why they have the ISF feature on the amp. You get a pretty wide tonal range out of it. I think for high gain stuff the US side sounds a little tighter and cleaner, where as I prefer the UK side for cleans/rock as you get a lot more body.
I think if you are in the market, you should also check out the Krank Rev Jr, and the Orange Dark Terror. The newer Krank's are cool cause they have separate gain/volume knob. The older ones had one knob for both clean and dirty. Someone on the forum just got in a Dark Terror... don't remember much about it tho.
