This guitar lick is a sequence of alternate picked sextuplets (that is 6 notes per beat). To really benefit from this exercise you should start slowly with a metronome and gradually increase speed. In the video there is a bit of extraneous string noise - pluggin my guitar directly into the computer seems to exacerbate this issue along with my high action. That or I need a few good days in the woodshed! Have fun and feel free to post your own version of the lick as a response.
