While looking at more of Sister Rosetta, I stumbled onto this little documentary which is wicked good.
Thought her guitar might be a Guild also, but one of the Dixie Hummingbirds said her axe was all metal so I thought it might be a Wandre a la Buddy Miller, but who knows? There are some other vids of her playing what looks like a 335 E but not totally sure.
This is really good, though. It is also the first of I believe four 15 minute clips, so if you like this, there is more on YouTube….
