This deviates a little, but is still on subject of oddball guitarists.
A guy bought a USA '62 RI in a shop up here many years ago. A day or so later he was back in with it, saying "..something isn't right with it!" The guitar-tech looked it over and could find [i]nothing[/i] wrong with it. The guy kept on bringing it back in. The 'issues' began to range from weird howling sounds to speech and then radioactivity!! The shop said, since they found nothing was wrong with it, they could not order another, whereupon he said "Take it, then; I don't wan't it!" and just left it on the counter!
The next day, he came back in with a bunch of MESA/GT valves and, again citing radioactivity, left them on the counter and disappeared forever.
