One guy can ruin an instrument. Jimi Hendrix, bless his heart - how I wish he was still around - almost inadvertently ruined guitar. Because he was the only cat who could do it like that. Everybody else just screwed it up, and thought wailing away (on the guitar) is the answer. But it ain't; you've got to be a Jimi to do that, you've got to be one of the special cats.
