Hey Bart! Let me point out the exact notes that I'm using my finger plucks on. All other notes I'm using the pick:

The first bit (at the 12th position), I'm using a pick for everything before sliding down to the 9th position --- however, you could use your finger to pluck the B note - 12th fret of the B string there.

Next, I'm using finger plucks on the E note 9th fret of the G string, and the very next high E note 12th fret of the high E string. I end off this lick with a finger pluck on the A note, 10th fret of the B string.

Now you slide down to the fifth position, and I'm using a finger pluck on the A note, 5th fret of the high E string.

Then there's the final slide down to the 2nd position, and it's another finger pluck on the A note 2nd fret of the G.

Hope this helps! Let me know if you have any more questions!
Mike
