This lick is completely major based, using both major pentatonic and mixolydian notes. It can be used for both blues and country playing, but for rock as well.
In this lick we will concentrate only on the I-IV move in the harmony. You can hear that the backing only alternates between E and A chords in the bass line.
I used Amplitube 3 software for this mini lick, tubescreamer and Mesa Boogie MKII emulations.
Guitar is a Fender Stratocaster, middle single pickup.
