Someone correct me if I'm wrong but I get the impression that this is not even close to "profiling" like the KPA does it. It seems like he is taking an existing amp in the Axe II and "EQ Matching" it (for lack of a better word) to the source. Not that this is bad or anything, I just think that it is an important point if this is the case. For example, what if you tried to "Match" a Fender amp block to a Marshall amp? I'm not trying to stir the pot here, I think the clips sound great, I'm just curious how this really works and what the limitations are.
