Oh my God, I thought about it, but now since we can see the label (the fact he left it on the guitar is insane though), it's pretty reMarkable.
So now he can play 95% of setlist on signature instruments — Fenders, Nationals, Pensas, Schecters, Martins and Gibsons. Man, I don't know if I'll ever be envier as NOW. Mark is Immensely inspirational human being indeed. Just imagine that... it's... insane.
