In this Sick Lick, I'm using the E pentatonic scale with the added major 3rd. This is one of my favorite scales to use when soloing. It creates such a unique sound and is very noticeable, especially when adapted to rock or metal solos. It's a great way to really throw the listener, as we would predominately use minor scales in rock or metal solo. The listeners aren't really accustomed to hearing the major 3rd.
