I teach this tune in my upcoming Lesson Pack Volume 9 https://www.daddystovepipe.com/guitar-lesson-pack-tabs-volume-9.php
Requirement tuning secret of E.
I blended two variations, the one he plays in the documentary movie “The Blues According to Lightnin’ Hopkins” and the one he plays in the dvd “Lightnin’ Hopkins Rare Performances” (released by Stefan Grossman Guitarworkshop).
I’m playing a copy of a Gibson L00 made by John Greven.
