is there a good training video on the Kemper - sort of a step by step ?

There are three basic tutorials from Kemper themselves, and if you tube-google for

kemper amp

you'll find practically everything there's around.

Also, see the video tutorials on wikpa.org.

If you are a bit familiar with the german language, i recomend the Workshop from Mr. Dill

This is a good video on Effects:

Lots of Kemper Profiler data here:

thank you OZ-LA

There's a great video of Gundy Keller tweaking a Pink Floyd tone with the Kemper. You should check it out.
