As you can see from the photo below, the serial number of my amp is C 09556.
MADE FENDER STRINGED INSTRUMENT For the majority of Fender's U. instrument production history, production dates have been applied to various components.
While this neck dating is useful in roughly determining the age of a guitar, it is certainly not definitive.
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.
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.
While doing research on Fender amps in general, and the Champ in particular, I came across the most amazing series of articles by Greg Gagliano on the subject. If you have any interest in vintage Fender tube amps, without question you’ve got to read them all.
The process that went into figuring all of this stuff out over 6 years and countless owners of vintage Fender amps is hands down an amazing story.
