I just played an old Guild F-30 today at Randy Woods. If I hadn't just bought my beach guitar I'd be seriously considering this one, it plays and sounds great. However it is really beat, this baby's been played. I wish I had thought to take a picture with my phone to post.
Basically there are a lot (and I mean a lot) of places where the finish is chipped or off. (back, neck, sides) There is a lot of wear around the bottom of the pick guard, clearly someone liked to strum and used a pick. I recognized the shape of the pick guard and head but had to look real close to see Guild on the headstock (I think it was stenciled). I couldn't find any cracks and like I said, it sounded great. It did have the label inside, I forgot to check for the serial # on the back of the headstock. It was made in Hoboken, F-30 SB, and as near as I could tell the serial number was A ? 2771 (I couldn't tell what was after the A, maybe a 2, maybe a dash.) It's on consignment for $625 including a gig bag so one for $300 sounds like a grabber to me.
I'm trying to see when it was made and can't figure it out based on the serial # and the charts I'm seeing. Can anyone help me with that?
