This amp is really fantastic. When i was looking for an amp to buy, i wasn't looking for anything too crazy, i just needed something that had a good sound, and some degree of dynamics or versitility without spending too much. Having said that, i feel like i should have paid a lot more! It has excellent tone, incredible functionality (head phone/line-out, CD/MP3 jack, built-in tuner), its loud, its customizable, and it has enough presets to make your head spin. Everything from Slipknot to 50s style guitar sounds are in this amp the moment you take it out of the box.
I havent had too much chance to play with setting up my own personal presets, but i have done a couple. I think there is something like 9 user customizable banks, with 4 channels for each... 36 user presets in total. It's just so much fun to play with! If you get this amp (or really any Line 6 Spider III amp) i would recommend getting a foot controller, i know im planning on getting the FBV-Express (i think thats what its called).
The only thing i think someone would fine undesirable about this amp would be the 'Smart FX Control'. To someone who is used to having individual pedals/effects for things like Delay, Chorus, Flanger, etc... you might find yourself wanting a bit more control. Personally, it doesnt bother me. But if thats the case for you, at the VERY least the 12 amp models will still provide a great array of different tones to start with.
