This just arrived on my end of the World... a 1991 S-500 Signature in cherry sunburst! She's reasonably light, scaling in at just under 8 pounds. (My Legacy is a whopping 9.2 pounds). Absolutely stunning swamp ash grain... not in completely mint condition, but used with a little real-world usage. Date stamp inside the tremolo cavity reads 72291. (I guess from 22nd July 1991?) Also has individual pickup routes under the pickguard. I'm still getting used to the tone... darker than my SC-3, with a bitey deep tone. She's a proud keeper in my G&L herd!
Very nice. I should come back here and browse more often. I have the lefty brother, manufactured prior to Leo's passing, and purchased from Dale Hyatt at the factory 'probate sale' in 1991.
The previous owner checked the neck & body date stamps: Jun 29 1991 for the neck and July 22 1991 for the body. As a little bonus since I received it, the previous owner also forwarded a letter from Dale Hyatt regarding the guitars entry in the G&L production log! ...I'll check the letter tomorrow & see what dates are mentioned (if any!)
I also purchased an unusual ASAT Signature from the same guy. I received that one a couple of days before my father passed away, so I haven't gotten my act together with photographing it yet. It has an unusual gun oil finish on the body as well as the neck! ...Also originally came with a letter from Dale about the finish used, but the previous owner has misplaced the letter for the moment (but he sent me a photo of the letter anyway). I'll get those posted soon!
