FYI - saw Pat last night in Great Barrington MA - one of MANY shows of his that I've seen over the years.
Sounded, well, just like Pat - Amazing! The archtop tones were big sounding; the guitar side of the Roland GR303 (or is it an 808?) - sounded great as well and sat perfectly well in the mix. Overall house mix was quite good and balanced as well.
Went up to the stage afterwards and can confirm that his rack has the Kemper featured prominently at the top... and really not much else in there.
Score 1 more for Kemper 
Go team!
