I'm going to bump my thoughts on the Kemper Player into this thread. I received a Kemper Player last weekend after the announcement of the Mk2 devices. I've been thinking of trying one out to revisit the Kemper stuff and as a small set and forget unit. Basically something I can plug into and dial up one of a few sounds without needing or wanting to mess with tones.
I like having the five rig buttons and some knobs to make quick adjustments. It would be nice to have a small screen on the unit but I think I can get around that if I keep it simple. I do think the knobs are kind of finnicky with the responsiveness and acceleration. Also, the switches have kind of a cool smoke grey color which I never noticed in pictures.
For the profiles, I tried a bunch and decided to use five different profiles from Michael Britt's "Crank N Go" pack. I picked five different profiles from the Friedman BE-50 Deluxe - clean channel, clean with a boost pedal, BE channel, HBE channel, and HBE with a boost. That seems similar to how I'd run the actual amp, and these profiles have less of that MBritt mid focused tone.
Now I've settled on the profiles I'll mess around more with the included effects.
