Played Canada Day in my town of residence(southern Alberta, at the time)a number of years ago. I had a killer bass cab that I had designed(all the local sound guys loved to use it, they could anything they wanted out of it) that was used by everyone. Drums - local wannabe said he had a "great kit" & showed up with an out of tune low-line POS kit. Our drummer, an old road dog, sat & tuned this garbage for close to an hour to get it to a tolerable point for the festival's events. Organizers learned, at least from this one!
