Do a search for *any* amp or modelling product - heck, Axe Fx. Look up frozen or dead on google. I'll be here when you're done. I bet you find some that had issues.
I really don't think that Kemper is the only company that has some software glitches. Line 6 products did/do too, I had a Vetta and there were several issues with it that they fixed with an update that took a year to come out. And some that never were. Plus remember we're on a board where people are going to come with issues. You can't look at the number of people on a board that have an issue and interpolate that into the unit as a whole.
I've gigged over 1/2 dozen times with mine, used it for jamming around the house, several rehearsals, moved it all over the place with no bag - I just put it in the floorboard area of my Challenger's backseat and go. I've even left the thing on over the weekend accidentally - no show stopping issues that I couldn't resolve fairly quickly. I've never had it crater/die on me either EVER or lock up.
It's a software product, people should think of it in those terms. If you want the most bug free solution from ANY modelling / profiling type amp, don't get one the first year or so it's out. It's hard for a small QA team to find every issue that all the users are going to find.Then again I work for a software company so maybe I'm just used to the development cycle.
Just my opinion.
