Based on my own information a few comments have to be made:

Some (perhaps even many) very early “modern” SG’s (1500, 2000 etc) have a serial number that doesn’t match the system above. They have the 1976 SG175 type 5 digit number.

Now the good part. History of Yamaha Guitars states that this numbering system is valid for SG and SX guitars. But also my SF guitars and my SC guitars (all 70’ies) match the above numbering system. I don’t know for sure but it looks like these guitars can be dated by the chart above too. Luckely these guitars normaly also have a pickup number that makes them datable.
