Using a G minor scale, I start on the low G on the E string (3rd fret) to the A (5th Fret) to the Bb (6th fret). Then I came with a right hand mute accent, into a double octave 16th note pluck from G back to the A and Bb thump.
Next, two thump mutes on the E string into a pull off/pluck of the Bb on the G string (3rd fret) to a hammer onto the 5th fret G on the D string. As with all of the lines play this one over many times making sure they sound the same after each pass.
