Yes all about the software... but forget what you know and have experienced from Line 6 to date. Helix's core modeling is a ground up new code base and new approach to modeling that has not been in any other device to date. Without first hand experience with Helix it's not worth speculating on how it sounds/feels... there's WAY too much speculating in this thread. If I picked up the vibe at the LA Amp show event... there really isn't a tremendous number of people that attend this thing. People that attended this are the only ones that have had first look at both items in the same day and most probably didn't play them both. I'm about 99% sure I'm buying an AX8 and will be able to have my own one-on-one with the Helix in the not too distant future. I hope to do some comparison with the same IRs loaded in each to get down to amps and amps alone... I'm not a heavy effects user and am not an "Ambient" player... either will satisfy me effects wise.. it's all about amps for me. I've never done a video review but it might be time to work out the mechanics and give a good, objective no loyalties to anyone review.
