I've been having a play with my AmpliTube (Fender version), and it sounds quite good. The only issue I've got really is that my floor pedals (Zoom G2 and G3) sound so much better. I like the idea that AmpliTube has got the store where you can buy just a few bits at a time, but to get to the level of versatility that is in even a cheap multi effects pedal will cost a lot. My G2 only cost me â‚¬29 from the second hand shop. The G3 has a low latency Asio driver built into it as well, although I usually use it plugged in as a stereo source through my little UR22 interface.
So unless I am lucky enough to win the full version I think I will just stick with my basic AmpliTube. And in Cubase I've got the AmpRack simulator which has loads more stuff in it, compared to the basic AmplpiTube that is.
