This is THE most beautiful guitar processor I've ever seen! It looks absolutely perfect. I had a TC G-System, but it was useless as far as external control's concerned - from what I've red so far, Helix far exceeds the G-System's capabilities.
I think the rack/pedal combo would be my preferred option, but from the start, I'm most interested in the controller. If it could be made to control MIDI over USB like the FBV MkII, I reckon you'd sell tons! It's like a really sleek version of Livid's Liquid Foot. I'll see if Ideascale lets me add that as a suggestion ;-)
Is the rack version 3U or 4U? Can't quite tell from the pics.
Plenty time to save my pennies ;-) Looks like I picked the perfect time to sell my HD Pro X!
