Here's a recent (5/15/2014) review of the Kemper I just found online. It's lengthy, well-written and honest - from the reviewer's perspective. But I also feel like it misses the boat. Thoughts?
(Full disclosure: I know Andy and consider him to be a good chap, but addressing his concerns and walking him through the issues he was having wasn't enough. He returned the amp after only a few days. )
