I got one of these as a present when I had to move in with a mate as I got a new job in stoke and couldn't take my Powerball and 4x12 with me. You can get some OK tones out of it with fiddling. Through headphones or good computer speakers/monitors its better than a pod xt and you can get some reasonable tones out of it but it still doesn't have the 'feel' anyway near that of a valve amp. I find to get a good high gain tone you quite often have to cut quite a bit of bass using the EQ to stop it getting muddy, also the JCM800 sounds like an angry legion of wasps which is very dissapointing.It does sound way better through a valve power amp and proper speakers but then that kind of defeating the object for me as I use it for 'quiet' practice and if I'm going to be using a valve amp I would use the Powerball.Yes the presets are shocking and it does sounds better with the volume rolled off a bit on my Tremonti's as it doesn't seem to like hot pickups. The dual amp mode is cool, I like to mix an Uberschall and Dual Rec together and it does sound pretty good. and using the dual amp with the same amp with different cabinets and/or mics is a good way to fill out the sound a bit.Basically without getting an axe fx there isn't much better out there. But for the price I probably wouldn't buy it if I was paying for it.
