Fender Jazz markings on neck

Recommended Posts

I'm about to sell my 1972 Fender Jazz and have been giving it a bit of a spruce up as I haven't used it for many years when I noticed some markings on the neck which I can't make out - see pic - any ideas as to what they are? Thanks

Thanks CamdenRob
Pity though that it's so faint but the serial number dates it to 1971 which is what it's supposed to be - I bought it in 1972.

The marks will be the remnants of the date stamp. There are often other stamps in the neck pocket on the body and on ther underside of the neck with the quality controllers and builder's name or initials on them .

[quote][size=4] [b]Dating 1970s Fender Guitars by the Neck Code[/b] [b]By Greg Gagliano[/b][/size]

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.
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). The new code consisted of 6, 7 or 8 digits and was usually stamped in green ink. 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. Both type of stamps can be found on Fenders made from 1969 through 1971. To clarify, a neck would have one or the other type of stamp… not both. 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. 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. Again, a neck was stamped with either the new type of code or the old date stamp, but not both.
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. He found that part of the codes denoted neck type. I used this information as the starting point for my research. I examined and/or received information regarding stamped codes for about 150 Fenders made between 1967 and 1980. Of these, less than half had useable information. In most cases, the stamp was smudged beyond legibility or the stamps were incomplete. Many guitars had no stamped codes at all. 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. First, the chances of having an intact stamped code is about 50-50. Second, my data set for making conclusions is relatively small and therefore, subject to change as new information surfaces. However, the interpretation of the two date code systems appears to be relatively straight forward and the conclusions were confirmed by pickup dates and pot dates in most cases.
The date from 1969-71 stamped codes can be extracted by working from the outside inward. For example, let’s take Telecaster Thinline (s/n 272207) with the code: 3320119B. Starting a the right we have the letter B. This appears to be the same neck width code that Fender had been using since 1962. 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. 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. For Stratocasters it is 22 and for Precision Basses it is 5. The other three digits (320) are a mystery and perhaps are some kind of batch or lot number.
Let’s practice that again okay? Here’s our P-Bass again (s/n 277983) with the code 529129B. Breaking up the code we get:
5 = code for Precision Bass
291 = batch or lot code?
2 = February
9 = 1969
B = 1 5/8 inch neck width (correct for a ’69 P-Bass).

One more time, since you love this stuff… Strat (s/n 279515) with code 22384109B. Break it into pieces:
22 = code for Stratocaster
384 = batch or lot code?
10 = October
9 = 1969
B = 1 5/8 inch neck width

Exceptions do exist. A few Telecasters have shown up with neck codes that would indicate a 1967 date and one has been reported with a possible 1968 date, yet the rest of the guitar appears to be from 1969. If Fender used the coding system as early as 1967, then we should see more 1967 and 1968 guitars surfacing with the green stamped code. One plausible explanation is the use of leftover necks – Fender is known to have done this often. If you have a guitar or bass with this first style green code and you would like to submit it to the database I’m compiling, please send the model, serial number, code, and if you have them, the pot dates and pickup dates. Additional information is needed to test the decoding theory and your help will be greatly appreciated.
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. We need to break the code up into pieces. The first 6 digits are paired off and the last two digits are taken singly. So that gives us 49 00 21 5 3 where:
49 = model code (Musicmaster, Mustang, Bronco)
00 = neck code (rosewood fingerboard)
21 = week code (week 21)
5 = year code (1975)
3 = day of the week code (Wednesday)
Now, how the heck are you supposed to know the model codes and neck codes? Well, I’ll give you the ones that I know so far. For model codes (first pair of digits):
01 = Precision Bass
02 = Jazz Bass
04 = Mustang Bass
08 = Telecaster Deluxe
09 = Stratocaster
13 = Telecaster, Telecaster Custom, Telecaster Thinline
49 = Musicmaster, Mustang, Bronco
For neck codes (second pair of digits):
00 = rosewood fingerboard
01 = rosewood fingerboard
03 = fretted maple neck OR skunk stripe neck with rosewood board
10 = fretless maple neck
Set up your decoder rings with the info above and try your hand on P-Bass (s/n 647149) with code 01031051. You should get:
01 = P-Bass
03 = fretted maple neck
10 = Week 10
5 = 1975
1 = Monday
One more time and we’ll call it a day…. Telecaster (s/n S725092) with rosewood board and code 1303167?.
13 = Telecaster
03 = rosewood fingerboard on skunk stripe neck
16 = Week 16
7 = 1977
? = day unknown as digit was illegible
Again, the decoding hypothesis set forth here need to be tested further and any information that readers wish to submit will be greatly appreciated. The information needed is serial number, model, neck type, green or red stamped code, and any pot or pickup dates. The info can be sent to me c/o the 20[sup]th[/sup] Century Guitar offices at 135 Oser Ave, Hauppauge, NY 11788.
Many, many thanks to the folks who contributed data for this research including Jim Werner the Fender Collector Somewhere in Iowa, Hans Moust at Guitarchives, Jim Strahm and Matt Kesler at Midwestern Musical, Jay Keim at Harmonic Arts, and Tim Pershing the Fender Student Model Guru. Tim earned extra credit for suggesting the explanation for the day of the week code.

[i][size=1]Greg Gagliano, a researcher devoted to vintage and collectible guitars and amps, clearly has way too much time on his hands since all he seems to do is compile Fender green stamped neck codes and Fender tube amp information.

my '75 P bass has the green and red system but it's so worn I can't read it.I think it's a '75 because the pickup is stamped '75 and the serial number is about '75 too
not that the serial number is totally accurate.
In 1991 I changed the pots but didn't check the dates on them, because no one was interested in a '75 Fender at the time

Thanks for all the info - I've listed it for £2200 as I know it's a 1972 - the date stamp on the neck would have been a nice thing to have if it was a bit more legible. Thought about playing it again but the fingers aren't what they once were so best it goes to someone who will. Still got a 1981 Ibanez Roadster which I may still play - it's in better nick than me - one day maybe......

I came across a 1969 jazz neck on sale on Facebook and then found this thread to verify the number. The neck number was "34090" on the back that does not seem to match the schema mentioned above (not to mention the truss rod screw seems heavily mangled although the seller claims "truss rod works well")

any ideas? here's a screenshot of the back of the neck:

That doesn’t look right at all. The neck looks like it’s been refinished (all Vo rage Fenders I’ve owned have aged on the back of the neck but less so on the part screwed to the body). The truss Rod doesn’t look correct either.

Didn’t most of the 60s jazz necks have the date stamp on the end of the neck like this

The sale ad mentions: "The neck has received a veil of transparent finish over it" 

All the google image results for Fender 69 bass neck do have the date on the bottom of the heel below the truss rod (like in the reply above) - the absence of it makes this neck very odd

It's still Fender, so who knows which variations there might be. My 71 jazz neck only has a non-saying pencil mark on it, without any date stamps (or they must have faded).

There are a lot of pics on the FB sale listing - not sure if I can copy more photos over here. 

It is listed in the European Bass Market page as '1969 Original Fender Jazz Bass Neck (with Tuners and String Tee)' for 1100eur. 

I was tempted to buy it but even more than the inconclusive neck number, the damaged truss rod nut made me decide to ditch it. Will leave it at that.

Probably for the best ,not worth taking the chance on the truss rod

I thought all the options for phrases to downplay "refin" had been exhausted.
