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).
Both type of stamps can be found on Fenders made from 1969 through 1971.
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.
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.
