I get really offended by that "Why do you have to tune" crap. I know several players who don't. Oh Jesus the cacophony that results. Indeed I sometimes don't myself, because of the shibboleth. I always regret it afterwards.

GO AND GET SOME SODDING EARS AND RECOGNISE THAT THE PEOPLE YOU DENIGRATE (I KNOW WHO YOU REALLY MEAN) ARE SOME OF THE GREATEST GUITARISTS ON THE PLANET AND WHO UNLIKE YOU YOU CLOTH EARED MORON DO NOT PLAY OUT OF TUNE.
