If you have followed my 8 finger Tapping lessons before, or my Sweep Picking 8 Finger Tapping lessons to be more precise you will know that to go from the Sweep picking technique to the 8 finger tapping technique I slide the pick up the index finger with my thumb. This is key to be able to combine those two techniques in the same lick. The most tough and the part you will probably have to drill again and again is the part where you descend the 8 finger tapping scale from the B string and back to the A string, of in other words, when you descend the minor scale pattern. Going back to the A string with the little finger and then do the correct intervals takes a lot of practice, so for mastery be sure to play just the descending part again and again until you are satisfied with the sound. Good luck
