Ok...first impression is that the Ultra channel gives that hot rodded and then some Marshall sound. A+
Haven't spent much time on the clean, but the little I did it was better than most Marshall's I've heard.
On the down side, the digi reverb outright SUCKS! lol That's ok, I have some nice 'verb pedals that go nicely in the loop. The plate 'verb on my Digitech Polaris gets me in that =\//-/= zone real nice.
