Just got my AX8 yesterday, so, obviously, I would Love for a newer version to made available anytime soon .. No, I really mean it!!
..so impressed am I with this AX8 that an AX8.5 would be immediately placed high on my wish-list. .. Just ..umm .,.throwing that out there for all the bean-counters at Fractal to consider. ...And ...I'm sure I'm not alone.
Personally, I like not having an expression pedal attached for all the reasons previously mentioned by others. JM-own-O..
Would like to see maybe an upgraded UI - though, even having considered a Helix, I'm actually fine with the original and smaller screen. There's always room for improvement, but that smaller screen does the job for me.
I Would like more IO - some sound and recording mojo via USB would be great, another stereo FX loop, etc.. More HP under the hood (naturally), and a couple more footswitches to get Witchy with.
I think we have reached a tipping point, to where software being vastly upgradeable, we are only being held back now by form-factor design and the processing power of these units.
I weighed the Helix and the AX8 over the period of about a year while I waited for the new Boss unit to come out - personally speaking, neither the Boss unit or Helix really inspired me to buy it, and I bought my AX8 knowing that at any-minute something better might come along. But, honestly, I fell in love with the sound of the AX8 over all else on the market.
Color screens and scribble-strips are nice, but when the rubber meets the road, that chassis has gotta be bomb-proof, and it's what I end-up hearing that inspires me to play..
So.. yeah .. Just my buck-forty-nine... Each to their own and YMMV, etc., But, any form-factor upgrade of this unit is gonna be gravy for me. Saying all that, I wouldn't hesitate to buy another Fractal floor based unit; because as good as this original unit is? ...phhhh ...I can only imagine of what 's to come from these good-guys who're busy breaking ground for us at Fractal.
