I was born and raised in Nashville so I know a few guitar players. A few hundred actually. But I don't know too many that have a college degree in the instrument. My neighbour Steve Elder does and that makes him a rare breed. And Gabriolans, he gives lessons so if you're motivated, you too can learn this uber-cool F#13th chord. He operates a recording studio as well so you can study and then create an aural document of your progress.
Note: My whole life I have made 13th chords by grabbing the low E string note over the top of the neck with my thumb. I had no idea I was doing it wrong. Thanks Steve!
