Eric said that if I could do only one thing, then I should practice my scales. So, I took his advice and chose the minor blues scale. What I discovered was that if I learned that scale, then I could play many of the solos of great classic rock guitarists from Eric Clapton to Billy Gibbons and, maybe someday, even Eric Johnson. That scale became my ONE Thing for the guitar, and it unlocked the world of rock ’n’ roll for me.
