Tony Levin was using a Kemper unit on tour with Stick Men this Spring, for his melody side. Looked like a Profiler Stage.

I received my Profiler Stage on Friday afternoon.
It's an amazing tool and no regrets on the purchase.

So far, I've been testing it with the PRS Custom 24.
The tones are very impressive, unlike anything I've ever seen.
I don't have internet at home, so I'll have to spend some time
downloading the Rig Manager and learning how to set it up for the Stick.

I decided to purchase a Yamaha FC7 expression pedal for my Kemper Stage.

The Kemper has a morphing technology that allows for the smooth control
of unlimited continuous parameters to blend amp settings, FX, and levels.
