I would recommend getting one of the pedals with it as well, either the express or short board. As well as getting a cheap memory card for it. You'll need that for when they have firmware updates, or if you want a bit more of recording time.
The only complaint that I do have with it is the size of the digital display. Could be bigger, but then again it's a friggin amp, not a laptop! ;-)
It's better to regret something that you have done than something you haven't.
