Wow Mr Brown you sure are very technical in your thoughts.
True enough, lol. In the end, first-hand experience will be the deciding factor, but I like to make informed decisions.
Very often means a few times a year.
Do you want a head to head between how many updates on the Kemper VS the Axe-FX?
Nope. I just wanted to know if the product is consistently updated (I have no reservations about this now).
I have full time professional session guitarist studio owner clients who have had their Kempers for 3 years and don't even know how to do an update....why?, because the Kemper doesn't need an update, it sounds the same today as it did in January 2012.
I understand what you're saying, but the Fractal folks say the Axe sounds better than it did when it was released. One could look at that as, "it didn't sound very good to begin with", or as "they've improved a good product even more." I'm not saying one product is better than the other, just saying sometimes the things people claim as strengths or weaknesses are relative to perspective.
