An ascending guitar run based on the E Mixolydian Mode. Try this over an E7 Chord. This lick uses legato technique with lots of hammer ons. Try to make it as smooth and flowing as possible. You can also vary the guitar lick by muting and picking some of the lines and using legato on others. This use of contrast is a good way to spice up runs. In the video and tab example however, I've stuck to straight legato playing.
