Where he slides is often the relative minor which is three frets down
from the original blues scale, and within various boxes and extensions.
Plus he makes stuff up constantly.
Jimi rarely stayed within the box- as it were.
He was never a mere player of scales
Did you learn villa and little wing from tab or listening?
I recommend listening after tuning right to the song-
and using tab only when you get stuck.
Much tab I find on the net is pretty well off the mark - except for here.
Try a little Nuno from III sides, for a change,
if you really want to pull your hair out of your head.
Good Luck
Merry Christmas Jon
