The last thing I ever would have expected is simple hardware issues. If I buy one of these I'd expect it to be able to take life onstage for years, but the reports I'm reading suggest it's under engineered for that use or the manufacturing is way out of spec.
I'm sticking with the remote until I've got confidence that it's robust enough.
I am sure the Kemper stuff will fix the issues and it will be a reliable tool.
But I have to admit that it is not what I would have expected too. After all possible competitors have already come up with a floor unit (from expensive too cheap) with no problems and all with perfect working editors right from the beginning- Kemper is not only late to the party. But there are (temporary) hardware issues, so people have to send their Stage back, are insecure about the durability and have to deal with a beta software. And a floor unit entering the market with no editor right from the start (wasn't ready in time).
Not exactly optimal!
What will save the success (in my opinion) is the still unrivaled quality of sound.
