My guess is that the signal of the kemper is less rich than the signal of a real amplifier, that's why it sounds so "dry" and "numeric" in this case.
The intermodulation of a real amp is smoother. There are more frequencies.
Someone could compare the profile with the real amp.
lol, it's interesting...Rob Chappers didn't hear a thing when he Profiled and played the Cornford for ages in the video.
He did crazy bends, he played the shit out of the guitar, yet he never heard this numeric intermodulation, not once.
I'll stick with my original call of....BS.
I think we need some intonation repairs done around here.
