A lot of people come up to me and say, “Satchel, you rock! You know all 28 frets of your guitar, man!” And I say, dude, are you stupid? My guitar only has 24 frets…or something. I don’t remember how many frets my guitar has. But the point is that I know how to get up and down my neck, and how do I know that? I know all the scales and all the arpeggios, and all of the positions of all of the modes, in all of the keys.
