I've been thinking of getting an Axe-Fx to replace my Egnater M4 rack setup. It would save me from having to schlep around a ton of gear, but I was wondering how difficult it is to program. I've used rack gear for over a decade but admittedly am NOT a big tweaker. I find sounds that I like and use them or tweak them subtly for my tastes. I don't have problems tweaking amp knobs to get tones that I like, but I'm not entirely comfortable tweaking rack gear with too many parameters. Is the Axe-Fx user friendly even for "non-tweakers" like me?
