I spent 4 months tweaking the hell out of my Axe-Fx II just to get a decent tone.
Yesterday, I finally got a Kemper. I spent 4 hours from unboxing to recording amazing tones without tweaking a single profile except for moving the gain knob a tad. It was everything I was searching for!
In my opinion, the Axe-Fx is missing the organic feel and upper harmonics of a tube amp. This may be due to cabinet IR's in general.
