When I sold the ones I had the buyer checked the potentiometers to date them.
Aha! Didn't know about that. Don't think there's anyone here where I live that I think would know how to do that or be reliable. Who would I ask? All I've got locally is (urk) Sam Ash and Guitar Center. I know I'd have no problem getting any one of many geeks in NYC who I could ask about that. Might you have any suggestions?
As an irrelevant aside, my parents bought my first instrument, a flute, for me when I was 8, at the original Sam Ash store in Brooklyn, which I can still recall. I was very excited to get that flute and start lessons.
The other guitars I've kept are a Martin 1967 12-string D-12-20, a Martin 1972 D-28 (bought new, I'm the only player and owner), and I still have a nice Fender Bass. My Music Man Sting Ray I got stolen in my move here, unfortunately. It disappeared between the moving van and the storage unit when I looked away for a minute or two, and I didn't find out till after they left. Funny how one of the guys had admired the case and had asked about it.
Oh yes, I also have a Ovation 6-string with a built-in pickup, bought from a friend, just for fun. Not sure how much I like it, but there it is.
Used to have a Dan Armstrong plexiglass solid body guitar with those funky plug-in, switchable pickups, but that was way too heavy on my shoulder to play for long, and the neck was a bit thick for my small-ish hand.
