"Reading the Blues" by Junior Wells and Buddy Guy has a pic of a Guild on the cover, but I've lost the CD itself and can't remember for sure, but I think it was acoustic. At any rate, I didn't like it, but I do like "Stone Crazy," which has a startfire 4 or 5 on the cover.
Son Seals' best Guild album might be "Bad Axe." It won some big awards. "Live and Buring" is also one of my faves of Son with Guild. His last (?) CD, on Telarc, has a Guild but imho he's off his game. "Son Seals Live" is great, but as I recall he did it on a Gibbon 335, and there's a Gibbon on the cover. "Deluxe Edition," his best-of, has a a picture of the 335, but most of it was from Guild recordings. His instructional vid was also on the three-turdy-five.
