So, after fiddling with one at last year's Musikmesse, I must confess I was most curious about this unit, and a demo unit conveniently placed at a friend's store allowed me to have my share of fun and experimentation with it, concluding it would best serve my interests than my AxeFX Ultra. Off went the Ultra, in came the Kemper.
One thing must immediately be said: working with an amp profile is not the same as working with a model, as the later attempts to capture the nuances of an amp and find ways to manipulate parameters just like the original would, being in essence a complex sequence of algorithms, whereas a profiling amp such as the Kemper will take a snapshot of the amp as you mic'd it, see what dynamic range it has and the frequency manipulation, clipping, etc., and create an exact image of that, while the controls allow you to tweak the profile using pre-determined values.
Let's fire it up!
As an example, using the gain knob alone, I managed to take a Marshall 1959 profile, taken with the amp at high volume, and add gain and pick attack to it so that I made a virtual Friedman from it. So, while you will want to take several profiles from each amp with your favourite settings for authenticity's sake (as they did) and proceed to use the extremely versatile tone shaping inside, knowing that the captured profile is indeed the departing point.
Calling Commander Buck Rogers!
Here's a video I took, with another pseudo-song. Since I was asked many times what good this would be for someone that, unlike me, doesn't have access to a multitude of amps and cabs to profile, the whole song was done with nothing but patches I created with the factory included profiles, namely those of a slightly scooped, not too gainy Dual Rectifier, a Mesa Roadking in Modern mode, and a 65 Amps London, all with the default cabs, and I even resisted using the SLO100 as usual. I added nothing but effects the unit already contains and this took no post processing except the raw mix. Hope you enjoy!

already said I loved the song! Might as well say it again... Good job!
