Ordered the Powercab to possibly replace my Friedman ASM 12. I haven't compared the two yet, but I did A/B with my Deluxe Reverb.
To my ears just running the Kemper into the Powercab on FRFR mode left me with a far closer'amp in the room' sound than did the Friedman. In fact, I couldn't tell that much difference.
I'll need to do a lot of tweaking to be able to use the cabinet models because they definitely color the sound.
But given my initial impressions, as opposed to the Friedman, and the weight difference (Powercab is easy to carry)...I'm probably going to stick with the Powercab.
