To clarify, a neck would have one or the other type of stamp… It is not known why Fender used two completely different systems at the same time.Then in 1972, Fender changed to a new type of neck stamp which had 8-digits which was stamped in green or red ink.The first one or two digits of the code, in this case 3, denotes the model.For Telecasters, Telecaster Thinlines, and Esquires that code is 3.Now that these instruments are hitting the "magical" 25-year mark, they have suddenly gained attention.
The other three digits (320) are a mystery and perhaps are some kind of batch or lot number. Here’s our P-Bass again (s/n 277983) with the code 529129B.
The next digit denotes the year, in this case 9 = 1969.
The next one or two digits denote the month, in this case 11 = November.
In 1969, CBS-Fender began to implement a new type of neck stamp in place of the usual date stamp consisting of model code, month, year, neck width (e.g.
8 DEC 65 B for a Duo-Sonic II with a 1 5/8 inch neck width).
