Dating yamaha guitars by serial numbers praying about a dating relationship
This information is usually found inside the sound hole of your guitar.Yamaha’s serial number system is one of the more complicated ones I have come across – so it’s a little bit involved.
The most common Yamaha serial numbers follow a system that uses 2 letters, followed by 5 numbers. The letters H to Q each represent the number that the year the guitar was built in .
Let’s look at an example of what this might look like – MM12022 From this we can tell that this is the 22 guitar built on June 12 of either 1966, 1976, 1986, 1996 or 2006. H = 1 I = 2 J = 3 K = 4 L = 5 M = 6 N = 7 O = 8 P = 9 Q = 0 But it gives no clue as to the decade so for each letter it could represent the following years.
Truss Rod Cover on Green Label and very early Red Label FG’s. WANTED – Could you please email me at Yamaha Vintage [email protected] 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. See Yamaha FG Serial Numbers, Interior Markings, and Labels – 1966 to 1981 for more information. Internal date code (I use flashlight and a cheap USB endoscope with my cell phone, or my cell phone camera if the strings are off.) This is very important to establish the date range of the serial numbers.
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.
