When I find vintage FG’s locally on CraigsList I will ask if I can see the guitar and take pictures. A few curious people I’ve asked have found date codes inside their guitars, but I can’t expect most people to go that far. He also has a website (in Japanese) dedicated to the FG-150.

I found a Japanese guy on YouTube who made videos of himself playing many early FG’s, and he mentioned the serial number and date code most of the time. But the date codes are needed as reference points.

Which I have many times as I’ve found more changes and differences.įinding serial numbers isn’t too hard. I’ve also recorded the link of where I found the data, just in case I had to go back. I got started by searching and asking for serial numbers and date codes and putting them in a spreadsheet. Currently I am up to 2600 serial numbers and 400 date codes. Once I discovered the internal date codes I knew I could compare known 6 & 7 digit serial number/date code sets with other serial numbers and make a good guess as to when other guitars were made.

The Date Code is typically next to one of these large numbers.

I had assumed those are detail numbers so they use the right side pieces for that model guitar, but I’ve found many inconsistencies, it’s probable they are inspection marks.

There is typically a single larger number ink stamped on each of the sides.

I’ve only found (2) FG-75 date codes, I have examined many and there were no visible internal markings other than the serial number.

The date codes are in most vintage Yamaha guitars, except for most FG-75/FG-75-1’s, some rosewood models (the wood is too dark to read it), and a few they forgot.

The visual quality isn’t as good as the cell phone camera but the length and flexibility allows you to get closer. Another option is a USB endoscope that is plugged into your cell phone.

The best way to find it is to put a flashlight inside the guitar and use the camera on your cell phone to look around inside.

The date code isn’t always visible thru the sound hole.

It seems not many people in the US know about the date codes, although they must be better known in Japan.

Some guitars did not get a serial number or it has faded over the years, so the only way to know about when the guitar was made is by this date code.

I’ve seen a few of guitars where the date code is partially under the kerfing.

This date code was probably stamped when they made the sides, not when the guitar was assembled.

Year 1 is 1926, therefore year 41 is 1966. In this case it’s the SHOWA period, the reign of Emperor Hirohito, which started in 1926. It’s the Japanese year based on the reign of the current Emperor.

The year isn’t the normal year we are used to.

The date code is located on either side of the lower bout.

Typically 3 to 6 weeks before it’s finished. This date code will be very close to when the guitar was built. While the serial number is visible, although not always usable to determine the date of manufacture, there is a Date Code ink stamped on the inside of all early FG’s, except most FG-75’s.

So the 6 & 7 digit serial numbers must not be related to date the guitars were built.

That didn’t work for a few guitars I found.

I’ve read the first digit in the serial number is the year, then a 2 digit month, 2 digits for the day, and the rest is a unit number.

What got me started was a curiosity of what the early (1966-71) Japan built FG 6 & 7 digit serial numbers meant. SEE THE POSTS IN THE FORUM FOR POSSIBLY MORE INFO.įOR INFO ON TAIWAN MADE FG’S SEE ABOUT HALFWAY DOWN THE PAGE. This article will be updated as I find further information.

They don’t always agree with Yamaha’s Guitar Archive data. The facts presented are based on personal observations, data collected, and data donated. I’ve been collecting data and in most cases can tell when a guitar with a 6 or 7 digit serial number was made (within a month or so). Yamaha doesn’t know exactly when the earliest FG’s were made. And to be able to fairly accurately determine when they were made.

The purpose of this article is to solve the mystery of the early Yamaha FG serial numbers, internal markings, and labels.
