I nominate Marvin Dykhuis. I saw him 25 years ago when my Dad took me and my sister to see a Tish Hinojosa concert in Grass Valley, CA. I was 12 and had gotten my first guitar about 6 months earlier. I was ruined after that, how could I want to do anything else but play country guitar?
I couldn't find any good videos of him picking fast, but he sings great too
Nice guy, too!
