Yamaha Bass Serial Numbers
Yamaha Guitar Serial Lookup
The earliest serial numbers I have are 40610478 (6/10/1974) & 0539508. The latest are 50830182 (8/30/1975). The Yamaha Guitar Archive data says these models ended in 1974 but the last Tan label serial number I’ve found is 50830182 (8/30/1975). 2020 marks two related anniversaries for Yamaha Guitars: the 30th anniversary of Yamaha Guitar Development - our Los Angeles custom shop - and the 30th anniversary of the Attitude series. The signature bass of the singular Billy Sheehan, the Attitude was one of the first production instruments developed by YGD.
