Funny, that. I thought the CLX was the clear winner with notable mention for the 6534 and Nitrox, and found the rockerverb and blackstar to be among the worst!
I also like the VH4, but found it really lacking there compared to what I know it can sound like, and was ambivelent about most of the others; they all had some good things going for them, some bad, except the randall and H&K, which were flat out dreadfull.
