I liked Leo's video with the null testing. I think when the Kemper was designed, they designed it to be as accurate as possible. And as we all know, they did a very job. But there are other things that are more important than a little bit of accuracy. With the Kemper you can have a lot of great profiles from people like Michael Britt, Bert Meulendijks and many others. And I think the Kemper Stage and the remote are designed very well. On stage - and in combination with the morph function, I have access to a lot of different sounds with just one or two clicks. No other 'capturing device' has these capabilities.
But after watching Leo's video it is a good idea to watch this video: https://youtu.be/elAiYDYyWQY?si=0Zbl52EmJMcVqdD_
