Dating a fender amplifier with serial number
Another method of dating a tweed Fender Champ is by serial number.
On my 1959 tweed Champ amplifier, the serial number is located right in front of the fuse cap.
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.
Most notably, production dates have been penciled or stamped on the butt end of the heel of the neck of most guitars and basses.
Please note the introduction of the "S" prefix serial numbers.The neck date simply refers to the date that the individual component was produced.Given the modular nature of Fender's production techniques, an individual neck may have been produced in a given year, placed in the manufacturing warehouse and remained in stock for a period of time, and then subsequently paired with a body to create a complete guitar in the following year.Serial numbers have been used in various locations on Fender instruments through the years.They have been placed at the top of the neck plate, on the front of the headstock, on the back of the headstock, and on the back of the neck near where the neck bolts onto the body.
