As I have only just started to look into the KPA (been looking at the Axe-FX II as well). I have a few instant queries that I don't seem to be able to find an answer for.
As per the Line 6 POD HD500, does the KPA have a built in looper function and can it run dual signal chains which can be paned hard left and right or a blend of the two?
The POD HD500 is an obvious choice for me as I have been a Line 6 user for some time (Spider amps and POD X3 Live), but as I have the opportunity to get something a little more sophisticated, the two front runners are the Axe-FX and the KPA (unless I'm missing something)
Also, has it been confirmed that a dedicated foot controller will be launched for the KPA? (along the lines of the MFC-101)
