Imported Kemper profiles sound too warm and dull and nothing like the demo's

Jamo D Moore please open a ticket on the support page of our website to further investigate your issue. We will be happy to reamp one of your DI tracks using one of the TJ rigs to see if we get a different result than you.

I do like some of Top Jimi's profiles, but they have quite an unusual sound, presumably due to how he mics them up - good for vintage styles, but I generally find myself using other profiles for recording. I had to try a lot of different profiles before I find ones that really worked with my guitars and styles of music etc - it may just be you need to keep looking? As for tweaking them, my experience is that once you've found great profiles, you can always tweak to make them perfect - but that if a profile's really not sounding right to begin with then, there's only so much you can do.
