Here is a 1977 PU-0 that has a "1" code so may have been a new model at the time. It measures 7.81k.



Correct me if i'm wrong but Greco had 3 catalogs in 77 Vol 6, 7, and 8. Pu-0 is first mentioned in vol 8 which would likely be the ass end of 77 so those pu-0s of Wulfs are aug 1977 which would fit in with being a prototype?

And the pickups of mine, Serial 15.12= Dec 12 1975 so we could say the guitar is likely to be from very early 1976 and the pickups could well be a prototype of U-4000's which came out mid 1976.?

Would be good to find more examples.

It is a bit odd to me that a prototype would have the "PU-0" already stamped in the back though, you would think that would happen with a production model only. Just saying, I don't know what it all means.

I do remember (to finish this sentence!) someone with early PU-2s that had PU-2 stamped on in ink rather than embossed. Can't find a picture though.

You do remember?

Yes that and I just found two different sets of pickups with the same serial, one set has u-3000 stamped the other set has nothing stamped and the serial number starts with 1 from 1976. u-3000 started earlier than that so I don't know what it all means either.

Hmm not much makes sense really. The only thing that has any merit is the supposed Email from maxon that they are production line numbers. There is no rhyme or reason to the first number. I guess it comes down to what ever had to be made on any particular day or week due to demand determined what production line they were made on, hence variying numbers on the same model pickups.
Nothing else fits.

As for number 1 being a prototype, maybe there is merit to that too but as with most things from this era there are exceptions.

Here is a copy of the email
Dear Michael,

Thank you for your enquiry. We made the pickups for Greco and Ibanez, etc. Please read the attached article from the UK magazine "GUITAR BUYER" for detailed information.

Maxon guitar pickup serial number consisted of five-digit number.
Period used: up to and including 1977
The serial number: ABCDD
A: production line code (1: prototype line (very rare pickup), the other numbers are the production line numbers.)
B: year of manufacture (e.g. 1977 was shown as "7".)
C: month, 1=Jan ... 9=Sep., 0(zero)=Oct., X=Nov., .(dot)=Dec.
DD: day of the month (01 to 31)
If A is 1 (prototype line), B is the year code and CDD are not disclosed.

Maxon guitar pickup serial number consisted of six-digit number.
Period used: After 1977.

The serial number: ABCCDD
A: production line code (1: prototype line (very rare pickup), the other numbers are the production line numbers.)
B: year of manufacture (e.g. 1977 was shown as "7".)
CC: month, 01=Jan ... 09=Sep., 10=Oct., 11=Nov., 12=Dec.
DD: day of the month (01 to 31)

If A is 1 (prototype line), B is the year code and CDD are not disclosed.

Here is another for info as well

Dear Michael,

We tried to find the old technical information and checked thoroughly about all the pickups. However, there was no information that we can trace from model number such as U-4000. All the information we have in the warehouse is just delivery numbers for guitar assembly factory.

All the information we can provide is as follows.
Alnico3, Alnico 5 and Alnico8 were used for Alnico pickups. For Ceramic pickups, Ferritic2 and Ferritic3.2 were used.

Regarding the serial number, we sent you the information before. That's the all the information we can provide.

Best regards,

What about this, it has me a bit confused too.

"If A is 1 (prototype line), B is the year code and CDD are not disclosed"

CDD are not disclosed? So a prototype pup serial would read AB with no numbers following.?

Yes, i think your right, in what she (Miyuki) is saying. A prototype pup would likely have only 2 digits showing, that being of the prototype number 1 and the number for the year only.

The prototypes might be stamped, for example, 15 (1975) or 16 (1976) or 17 (1977) and so on.

I have not seen a pic of a prototype pup, ....... that would sure help.

(sorry about edits)

Ah I'm glad you agree coz that makes more sense about them being very rare and any like mine or wulfs starting with 1+bcdd are just normal production line numbers.
