So I finally did a little research on my $50 flea market Yamaha. And it seams that "El Kabong" is somewhat of an item. The FG 331 is obviously the model # but the made in Taiwan sent me looking at serial #s that go back to the 70s. According to the Yamaha web site my #: 01017314 means my little banger was built in 0 for 1970, 10 for October, 17 for the day in October, and was the 314th unit produced that day. 0-10-17-314. Considering that it looks and plays like a new instrument has me in awe. My guess is that somebody bought it as a starter and quit real quick.
