I just got a Line 6 Helix after using a Pod xt since 2005. I've only had it a couple of days, but I'm fairly shocked at how great it sounds. Also, I'm overjoyed at how much fun it is to use. It's really just pure fun putting sounds together on that thing - the interface is superb. You think, oh...
I'm on the fence between the new Line 6 Helix and a Fractal Axe Fx.
I found these four videos about them but I still need more information.
Videos I am referring to can be found on youtube if you type the search words Fractal Vs Helix
