Ideal for touring bands. The Kemper has allowed us to do a sound check, all on and off stage in 15mins!
We have 2 Kempers and have the line and cab level de-linked, so the stage volume is independent of what is going to the desk. This was a very complicated setup with tube amps previously, as fantastically as they sound and look, this made life hellish for setting up quickly.
For recording, it's fab to lay down tracks and send profiles to our mixing engineer, with a very close the idea of the sound we're after.
My only con is the 44.1kHz sampling rate, and would like it to have the options for higher rates; as I'm a stickler for high sample rates, like to have "air" in my recordings, and that many audio interfaces are now offering up to 192kHz and over.
