Hmm - did some reading - the Mini Colossal, while it looks like it could be a decent proposition in its own right, I think the 'JSX' brand is misleading.
Folks should beware,on paper, this looks to be an entirely different beast to the JSX head, which has clean, crunch and ultra channels (an extremely outrageous lead hi-gain sound which I was hoping we might get a bit of replication of in the Mini). Instead, it's a Class A with "a pure, wide-open sound, classic tremolo" which says something else to me...
<edit> anyway - let's wait and see when we can try one out - the site does say "can run clean, crunchy, or down and dirty"
