Some time ago I approached the guitar player of a really great cover band which was playing at our company's summer party. He had a Kemper on stage and I asked him during a break what profiles he's using. He looked at me sooooooo puzzled and super surprised. Very nice conversation then and he admitted he never had something like that before - because audiences simply do not care if they are not very full of musicians (or even full of guitar players). So it is probably a bit different on music fairs or similar.
By the way: The answer to the profile questions was nice and along the lines of "uh... wait... not exactly sure... some 69 Marshall profile that sounds good and came with that box...". Needless to say he sounded perfect that night
Its funny but even after all the years I’ve owned the Kemper and bought loads of profiles just for the fun of it, I still use the stock MBritt 69 Marshall profiles as my default rig too.
