I uploaded a couple profiles to the Rig Exchange. It's the first time I ever did this so I hope they're done correctly. Sorry if they're not.
I did the profiling for both the Custom and Vintage channels with the volume set right where they started to break up. I then dialed back the gain a bit and played with the EQ and AMPLIFIER settings before uploading them. They're under my Author name ajmxbend.
The Kemper is indeed amazing and I hope someone can find either of these rigs useful.
