Fender amp dating code
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.While this neck dating is useful in roughly determining the age of a guitar, it is certainly not definitive.So, obviously a neck date, while being helpful in providing a date range of production, it cannot be a definitive reference.Unlike the auto industry which has specific model years for their products, most specifications for a given Fender instrument model, change little if any, through the lifetime of the model.There are several re-issues that look identical to vintage amplifiers of the 50s through the 70s.Look closely at the serial numbers and production code stamps to see if they match your Bassman model.Shortly thereafter, the Bassman would become the most sought after amplifier for country and rock guitar and bass players.
The only sure-fire way to date a Fender Bassman is by matching serial schemes.
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.
They were stamped on the back vibrato cover plate (early '50s Strats), and on the bridge plate between the pickup and the saddles on some Telecasters.

The serial numbers do not immediately reflect the change, as CBS continued to make instruments using existing, tooling, parts, and serial number schemes.
