Dating yamaha guitars by serial numbers
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 also recorded the link of where I found the data, just in case I had to go back. A few curious people I’ve asked have found date codes inside their guitars, but I can’t expect many people to go that far.
Yamaha’s serial number system is one of the more complicated ones I have come across – so it’s a little bit involved.
They don’t always agree with Yamaha’s Guitar Archive data. This article will be updated as I find further information.
What got me started was a curiosity of what the early (1966-71) Japan built FG 6 & 7 digit serial numbers meant.
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.
