It’s been a year since I did many changes to this site. The forum is the most up to date because it’s easier to add posts and pictures.
Yamaha FG Serial Numbers, Interior Markings, and Labels – 1966 to 1981 has had a major update with the data I’ve collected in the past year.
I also added Refretting a Vintage Yamaha FG, revised the data links for Serial Number – Date Code Chart, added more guitar weights to Yamaha FG Guitar Weights, and updated How to Properly Adjust the Truss Rod.
I’ll add more here as it’s updated.
