Well, I can confirm that guitar was still there at the end of last July.
Rainbow Guitars is a wonderful guitar store in Tucson that I went visiting some months ago while on holiday through Tucson, on advice from some members of LTG. I liked my stay in Tucson a lot, and visiting Rainbow Guitars I spent a couple of hours trying a nice 12 strings Rickenbacker, some Gretsches, and every Guild they had there, plenty of GAD Guilds, but also some beautiful 12 strings ,I guess an F412, and an F30. Then on the electric guitars rack I saw a nice starfire reissue and that old CE100.
If my meeory serves my well the price was really cheap but on the price tag it was written generically "'70s Guild CE 100" ,while it's pretty clear from the pickup and from the striped chesterfield headstock logo that it must be at least from the sixties, and from the pickguard it looks even older. I already own a 1966 Guild CE100D so I was a bit curious of trying another one, it felt good and comfortable, and pretty good acoustically, I didn't plug it to and amp though...
