DESCRIPTION:
http://txba.ly/v6Jh - Here's a simple way to ascend the fretboard from the low E string to the high E string, covering one octave. We'll use an element of my "5 Essential Blues Boxes" series called "The Backdoor Pattern" and a lick that allows us to transition from one pattern to the next.
