I posted on this thread back in June and I see the thread has been resurrected. I will add an update.
I previously was getting frustrated with my AX8 and being left behind, so I had bought a Helix because I loved all the buttons, layout, squibbles, plus an expression pedal all in one easy to carry and set up unit. But after purchase I was not happy with the Helix tones compared to the AX8, so I returned it. Since then I have investigated the Headrush, Quad Core, Boss GT1000, and see the Helix has come out with an update on their firmware. But every time I plug back into the AX8 I like it. Soooooooooooooo....
All of those options, except the Quad Core, have been on the market for several years, thus I am thinking a new generation of floor pedals may be on the horizon in the future, maybe even Fractal with an AX8 style floor board with more CPU??? So I have decided to wait it out. My AX8 still functions like a tank, never had an issue with it other than its obsolescence. ;-)
Every company is getting better. But I do have a warm spot for Fractal cuz i have been with them since the days of Ultra.
