The American Deluxe Series use the same dating code but add a "D" in front of the "Z", i.e. The following serial numbers are somewhat outside the more, well known Fender serial number schemes.
If you have what you consider to be a somewhat "odd" serial number, please check the following chart to see if you find your serial number configuration here.
There were periods of time when this was not consistently done, (between 19), and there are certainly other examples of short periods of time, and individual pieces, where the dating was simply omitted.
But due to the modular nature of Fender's production methods, and the fact that most serial numbers schemes are not sequential and usually overlap from between 2 to 4 years, (from the early days of Fender, through to the mid 1980s), dating by the serial number is not an exact science.As a result, you will see some 1990 guitars bearing N9 serial numbers Year 2000 introduced the "Z" prefix serial numbers on US made guitars, which stood for the 0 of the new millennium.A Z0 prefix dates to 2000, a Z1 prefix dates to 2001 etcetera.They are detailed reference resources with a wealth of information for helping to either establish the vintage of your guitar or bass or for just learning more about Fender history in general.These books are the same resources we refer to here at Superior Music to research answers to history and dating questions.
