I've always loved the interesting anecdote that Doc developed his now legendary flatpicking style while playing a Les Paul (electric solid body guitar) while he was playing in a Rockabilly band in the 1950's. Additionally, I've heard that he actually didn't even own an acoustic guitar at that time.
I've always wondered what kind of reception a picker would get at the National Flatpicking Contest in Winfield Kansas if he were to show up to compete with a Les Paul in hand!
Well, according to the rules, he could play it, he just couldn't plug it in.
