Watch the Bend & Descend online guitar lesson by Robbie Laws from 30 Penta Sonic Blues Licks You MUST Know
A minor pentatonic box pattern #4.
You're going be using some legato in this lick, starting out on the high E string at the 3rd fret with a 1/4 to 1/2 step bend. Hit the open E high string, which begins a 16th note triplet down to the G string at the 2nd fret. At this point, add some nice vibrato to that note.
Next you'll move to the open D string and hammer-on at the 2nd fret, then descending the A minor triad, reverse and ascend to the B string 1st fret up to the 3rd fret with a 1/4 step bend. Descending the A minor triad, you then tag the open G string and finish off at the 2nd fret G string.
