I've had the KPA for about a week, mostly trying out all the rigs. I've posted a few profiling attempts that seem to work pretty well for me.
Fender Hot Rod Deluxe clean (maybe too bright) and with a Carl Martin PlexiTone for crunch.
Carvin Vintage 16 clean and one with some gain.
Both were profiled with a Les Paul and WCR Godwood pickups and they have V30 12" speakers.
And I tried a few AC15's from a Digitech RP1000.
Hope you like them.
Sorry, just noticed there's already a similar suggestion already posted. 
Maybe a suggestion to help manage profiles -
Could the Browse function add user defined folders? Then rather than the long profile names to tell you what a profile is about, the folders might allow a way to keep them in order.
For example - Maybe create folders Les Paul, Strat, Tele. Beneath those maybe a folder for an amp like Marshall, Fender, Vox, then the profles you want in those folders. Or whatever folder names make sense. Maybe a ".." folder to move back a level.
Might make keeping track a bit easier.
