FOH refused to go direct out of the Kemper for me yesterday. Was telling me for like 10 minutes that he was experiencing guitarists using all sort of modelers and it all sounded like crap. Well, it was a festival, so no time to discuss. Played the Kemper through poweramp and cab then. I guess he didn't even notice
It happened to me last year, the sound guy dropped an sm57 in front of the Camper FR212 (the fact that it has a twitter as well didn't interested him). A moment that he was not looking I've unplugged the XLR cable from the mic and plugged it in to the main left from KPA. He didn't noticed anything 'till the end of the show....you must have seen his face!
No discussions since that evening
