Yamaha FG Serial Numbers, Interior Markings, and Labels – 1966 to 1981 The purpose of this article is to solve the mystery of the early Yamaha FG serial numbers, internal markings, and labels. And to be able to fairly accurately determine when they were made.

See Yamaha FG Serial Numbers, Interior Markings, and Labels – 1966 to 1981for the results of this search. My search expanded to also include the Taiwan FG’s.

My latest interest is decoding the mystery of the 6 & 7 digit serial numbers. It’s widely known that the 8 digit serial numbers start with the year as the first number. But the 6 & 7 digit numbers (located on the neck block) are just sequential numbers used by all the guitars they built, not just the FG’s. I’ve also found there are internal date codes that will reveal when the guitar was made.

I’ve started a list of guitars I’ve found (including 3 of mine) with the model number, the serial number, and the date code, which will allow the 6 & 7 digit serial numbers to be grouped into a range for each year, allowing any 6 or 7 digit serial number to be cross referenced to the year it was made.

On YouTube I found a guy in Japan who’s posted short videos of many vintage FG guitars, with the year, model number, partial serial numbers, and in a most cases the internal date code. He’s obviously used the internal date codes to determine the years. Ballad Maker on Youtube

With this, and other data I’ve been finding, I’ve discovered even though Yamaha says the first Red Label models imported in the US where in 1968, I’ve found many Red Label FG guitars made in 1967. I’m also tracking the Green Label FG’s, the earliest models (1966-67) only made in Japan, that share the same pool of serial numbers. I’m looking for the transition between the Green and Red labels. I’ve also found the Green Label FG’s have a different truss rod cover, with “Reinforced Neck” on it, very different than the one you normally see. That cover made it onto the earliest FG’s imported into the US, before changing to the familiar one.

WANTED – Could you please email me at YamahaVintageFG@gmail.com with the following data from your vintage Green and Red label Nippon Gakki FG guitars that have serial numbers less than 8 digits, located on the neck block? I have over 350 serial numbers so far, but only 38 of those have the internal date code. I’m also collecting data on Taiwan made FG’s, up to 1981.
