A while back there was a discussion about the Axe-Fx on the list, so I thought I'd mention a new product that, in my view, is pretty much its equal. It's a little scaled back (in a good way) compared to the Axe- Fx, and doesn't have as many amp models (yet), but the sound quality of both the amp models and the fx is stellar. I'm very, very impressed, and I am a tube amp snob (I own 16 or 17 exceptional tube amps, including 6 vintage AC30s).
Anyway, for those of you who are interested, check out the new POD HD products from line 6. You may find that one of them suits your needs quite well.
