Dating a fender jazz bass
The strange and mysterious neck codes found on Fenders from 1969 – 80 have been all but ignored by the vintage and collectible guitar community.Perhaps this is due to the fact that 1970s Fenders have, until recently, been all but ignored by the vintage and collectible guitar community.Again, a neck was stamped with either the new type of code or the old date stamp, but not both.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.
Now that these instruments are hitting the "magical" 25-year mark, they have suddenly gained attention.
I won’t get into the pros and cons of 1970s Fenders here, but instead, I hope to shed some new light on those weirdo neck codes.
An example of this is 02033923 found on a Jazz Bass.
From 1972 through about March 1973, this new system was used concurrently with the old Month-Year date stamp.
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).
