I examined and/or received information regarding stamped codes for about 150 Fenders made between 19. In most cases, the stamp was smudged beyond legibility or the stamps were incomplete. Some guitars simply had the model name, such as "MUSTANG" stamped on the butt end of the neck in green or red ink.This means two things for the owner of a 1969-80 Fender.For example, let’s take Telecaster Thinline (s/n 272207) with the code: 3320119B. This appears to be the same neck width code that Fender had been using since 1962.

Now that you’re all expert cryptographers let’s dive right into the 1972 – 80 coding system.

Example: Music Master (s/n 595121) with code 49002153. The first 6 digits are paired off and the last two digits are taken singly.

The next one or two digits denote the month, in this case 11 = November.

The first one or two digits of the code, in this case 3, denotes the model.

An example of this type of neck code found on a Precision Bass is 529129B.

CBS-Fender used this neck code system concurrently with the standard Month-Year date stamp that had been in use since 1962.After March 1973, Fender dropped the old style date stamp and continued to use the new style, 8-digit code until sometime in 1980 when small adhesive labels bearing Month-Day-Year date stamps appeared in the neck pocket, pickup cavity and/or back of the neck.Andre Duchossoir briefly discussed his findings for the 1972-80 codes in his excellent Telecaster and Stratocaster books. I used this information as the starting point for my research.Before the seven-year anniversary Instagrams or the 2009 Malibu wedding, Jenna and Channing Tatum were just two 20somethings unconsciously revealing how much they really, really liked each other on their 2006 Channing: Jenna's very, she's obviously beautiful, but she really, really is as beautiful inside as she is out. She loves to teach people how to not come from a place of insecurity, just, you know, come from a place of love, I guess. The strange and mysterious neck codes found on Fenders from 1969 – 80 have been all but ignored by the vintage and collectible guitar community.Both type of stamps can be found on Fenders made from 1969 through 1971.
