This time we have something cool derived out of the position 2 in A blues scale. We're playing over a blues boogie in A, so this lick would fit perfectly in something like Joe Satriani's "Satch Boogie"
This lick is taken from my lesson “Extended pentatonic licks”. It's in the key of Em and is in the style of Paul Gilbert, featuring combined picking and legato and using extended pentatonic shapes.
