So I've been using my Kemper for a few years now very successfully and it works perfectly within the context of my current country/pop/rock band where things are about polished production and making sure the singer sounds her best. Not to say that I sometimes don't miss my Boogie rig to the side of me (still have it all) but it's just so much easier, predictable - and lighter. And it supports my acoustic guitar in a great way also. One signal to FOH and done.
Now, it's starting to act up a bit lately and doesn't always power up all the way. Could be something with the connection to the remote. So I think it needs to go in for service.
That said, I think it's time for a backup. The Stage comes to mind given the form factor. I rarely use the power amp section TBH, so I'd be ok either way.
Question: I know there are some slight differences in the software. How easy is it to keep a head and Stage in sync? Can I use a backup on a USB stick form the head and just upload it to the Stage? What would be different and needs manual tweaking?
