Hi
My 2 cents ,I have had my kemper now for a few years and up until recently I was using a powered speaker namely a Yorkville parasource. It sounded good but lately something was missing. I decided to go the guitar cab route so I picked up a 2 12 greenback cab with a art power amp. Well I had to do some tweaking of course,turn off cab sims etc.. but its so much closer to a real amp and guitar cab. I don't know why I waited so long to try this. I find the tone cleaner and more what I am used to hearing a guitar amp and cab sound like. I can still run xlr out with guitar sim to PA and use my cab for my monitor and frankly most of the places I play live we go cab live anyway. It just feels like I'm more in the zone of what I want to hear.Also for me FRFR is nice but a guitar sits in such a narrow range I feel sometimes a FRFR is to much in that regard.
Cheers
