Ancient Mariner
It isn't. The guitar sounds fine until the end of the song. He also uses the same guitar for Icarus, TETMD and Hallowed in the same concert.Again, he switches the pickups around 3:05 in the Wicker Man video. Most likely, there was something wrong with the bridge humbucker that he didn't like. But yeah, kinda overreaction.
Also, there's the commercial aspect - someone could think twice to buy a signature guitar that is smashed on stage by the artist himself.
