Gotta say Quantum on the Axe FX sounds so good to me, I am getting rid of my Kemper. In addition, the foot controller and editor really add the professional control and reliability I want.
I've never been overly fond of the sea of tweaking options with the AxeFx gear, but I have a buddy who has one (AxeFx2) and have been able to play around inside the editor program a fair bit. I agree on your view of that - that editor is pretty damn slick!
Will be sorry to see you go Lasvideo, but it's great you were able to directly compare the units for some time before deciding which unit you prefer and what which controller would work best for you. Most people don't have that luxury!
