The chart below details Fender serial number schemes used from 1965 to 1976.
While there have been periods of dramatic change—such as the transition periods between the Leo Fender years and the CBS years or the transition between the CBS years and the current ownership—most models are generally feature-specific and do not change from year to year.
Serial numbers are also helpful in determining an instrument’s production year.
Notice that there is quite a bit of overlap in numbers and years.
The only way to try to narrow the date range of your specific instrument is to remove the neck and check the butt end of the neck heel for a production date, which may be stamped or written there (if you’re uncomfortable doing this yourself, please refer to an experienced professional guitar tech in your area). Serial numbering didn’t change immediately because instruments continued to be made using existing, tooling, parts and serial number schemes.
Most notably, production dates have been penciled or stamped on the butt end of the heel of the neck of most guitars and basses, although there were periods when this was not consistently done (1973 to 1981, for example) or simply omitted.
instrument production history, production dates have been applied to various components.
Therefore, while helpful in determining a of production dates, a neck date is obviously not a precisely definitive reference.
Most specifications for a given Fender instrument model change little (if at all) throughout the lifetime of the model.
For years, serial numbers have been used in various locations on Fender instruments, such as the top of the neck plate, the front or back of the headstock and the back of the neck near the junction with the body.
Serial numbers were stamped on the back vibrato cover plate on early ’50s Stratocaster® guitars, and on the bridge plate between the pickup and the saddles on some Telecaster® guitars.
But once again, due to Fender’s modular production methods and often non-sequential serial numbering (usually overlapping two to four years from the early days of Fender to the mid-1980s), dating by serial number is not always precisely definitive.The chart below details Fender serial number schemes used from 1950 to 1964.
