I have a late 70's F50R acoustic that I bought in 1986. It's been a player all along and has its share of battle scars. When I was living in NYC I wanted to get it spruced up a bit (the truss rod was out of room for adjustment and the action was getting uncomfortable). I asked around and ended up taking it to a shop on 48th. The little old man behind the guitar repair counter said, "Hey, that looks like one of mine," and Carlo Greco himself reset the neck of my favorite guitar (including new binding) and refinished it, installed a new bridge, and put a new label in the sound box (it had gone missing at some point). What a cool guy, too.
