I dabbled with a Peavey Vypyr + Sanpera pedal for a short while. Spec looked good. Turns out the design team were renegades from Line 6 (I was told). Anyway, it sounded pretty good - live it was totally unreliable due to the most bug ridden software I think I've ever come across. I only need an amp to play up once on a gig and then it's toast. To my mind, the simpler the better - any amp with more FX than a verb tank in it is not worth the risk.
