Well, as much as I love the diversity of all the Kemper profiles (cabs) I´ve either bought or got from the RE ...In 90% of the time I get better results replacing the cabs with my Ownhammer IR´s.
I have a 4x12 Marshall, a Mesa 4x12, and a 1x12 Fender. These pretty much covers all my needs.
IMHO the cab stands for at least 50% of the overall sound and I get so many consistent, good profiles, just by using these IR`s.
