Dating yamaha guitars by serial numbers

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.

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.

If you don’t already have your serial number, you’ll need to locate it and in some cases you’ll need to find out where your guitar was made as well – this information will usually be found next the serial number and will say “made in..” and then the country that the guitar was built in (either Japan, Taiwan or Indonesia).

But the complexity of decoding the number isn’t the most frustrating part of this particular serial number system – it’s the fact that the serial numbers actually repeat every decade – so you actually have to know what decade your guitar was built in to begin with.

Anyway, let’s start with how the main system works – if you don’t have a serial number that looks one of the ones in the next section, then carry on to the following sections for the less common serial numbers. The first letter represents the year that the guitar was built.

I’m also collecting data on Taiwan made FG’s, up to 1981. If it has the old style “Reinforced Neck” truss rod cover.

Any other information you’d like to share about the guitar.
