The Grateful Dead's Jerry Garcia is well known for his noodling, improvisational, and melodic style of guitar playing. If you didn't know
he's missing two-thirds of his right middle finger, there is nothing in his playing with either the Dead, The Jerry Garcia Band, or any other of his projects that would make you think he doesn't have all his digits.
The fact that Garcia was able to master the guitar even with only nine full fingers is likely due to how young he was when his brother chopped off his finger...as a kid, if you have a few little things that make you different, it's a good score.
So I got a lot of mileage out of having a missing finger when I was a kid.
