You have the 2 big guns (axe fx & kemper) to choose from.
I chose kemper and i know its the right choice, here's why.
A majority of those who purchase modellers for recording are not all that happy with their tones they are getting via microphone on speaker, fair enough! Not everyone has awesome cabs/mics/pres/rooms to get pro results. BUT, i have found those who buy a Kemper will still be inclined to practice micing and mixing real amplifiers via profiling. Lets face it, its fun having that days mic up trapped in your toaster sized box forever. And, its a challenge that has the ability to directly compare results at the flick of a switch.
Those who by he axe fx will be more inclined to use it on any sort of recording instead of micing anything up, hence missing out on the black art of micing amplifiers up.
Thoughts?
