Kingjimmi...
I would hold off for the AX8... because it's not going to be a lot more than the helix, and Fractal has proven tone. Metallica, Megadeth, and Steve Vai use Fractal.... plus I love what Tyler & Mark Day have done on here, that's all I need to know the tone is as good as real amps... Fender/Marshall anyway.
As far as the foot controller, lots of people on here say the FCB1010 works well and also the pod500x as a controller/emergency backup.
I think the $750 controller is one of the worst aspects price-wise of getting a Fractal Axe Fx.... I will end up forking it out though because as so many state on here, it's nice to have it be seamless and not have to program it... I am NOT a tweaker.
But I'd just wait till Ax8 comes out, then get them both if you have the means, try them side by side, return the one you don't want, no money lost, and then you have the peace of mind knwing you made the right educated choice.
