With everyone raving about the Axe-Fx and all the great demos I figure it's just a matter of time before I purchase one. Now along comes the II and many people are dumping the Ultra to line up for the new one. So Being a tube amp guy and having been burned by the lower priced modelers: Is this just g.a.s. or is the II going to sound even better? And if the Ultra can already really model the analog and tube gear we all admire without glitches how much more modeling is needed? Will the II offer even more realism and if so what does that mean about all demos and accolades about the Ultra's current realism? I've read the info at the Fractal Audio site, but what actual sound/tone advantage will this new one have. Putting cost aside, what will be the real advantage of having a II over an Ultra?
