Sure it's a classic, and done by a legend (for some anyway

), but I personally found it lacking quite a bit compared with what You find on You tube for example.
I'm a self taught hack player, so You can take my comment with that in mind.

AFAIK, the sound on the instructional video is miked, but on live and on the records Lee relies mostly on a magnetic PU with a FB click-PU for the combined sound.
