Cool Experience


Recommended Posts

First post!


Post in lots of audio forums and a number of Acoustic Guitar forums.


Although I own a number of electrics, been a while since I owned a Gibson.


Here is the cool story. In my teaching work my wife and I came to meet a very nice lady and the work caused us to know her very well. She found out I liked guitars and owned several. She said she played, but then said about 20 years ago she bought her son a really nice and expensive (to her) guitar and amp. Said her grown son still had it. She did not know what it was. Later told me she talked to him and he said he sold the amp for quite a good price but still had the guitar. She had him bring it to her when he could. Well next time she wanted me to see it.


Well it was a typical red Gibson SG, obviously older but in excellent shape. Obviously has some neck wear from playing but in really good shape. Told her I would take it and put new strings on it and check it out if she wanted me to. She said great and let me take it.

I put new strings on it and tweaked it a little, did not need much. Took it back to her. She said "did you like it" .. I said "of Course!"


She said well talked to my son and he said if you liked it and if she approved .... it it was mine. She gave it to me!

Pretty cool huh?


Now my question about the year. I'm thinking it is early 90's or so. Everything looks original.


The serial number is stamped into the wood with MADE IN USA also stamped into the wood on the back of the headstock


Serial number is: 90963566


any help on what I now have. Sure enjoying it ... it has been played enough to be really cool. setup is great. Loving it!!

Have a couple of G&L's what a nice contrast with this.


Thanks for any help you can give me about the year it was made... and any ballpark value.

96th day of 1993.





"Gibson USA, Gibson Acoustic, Gibson Memphis

- From 1975-1977 the number is typically found on a decal on the back of the headstock. This should be an 8 digit number that can be dated by the 1st and 2nd digits as follows:


99 = 1975

00= 1976

06 = 1977


- In 1977, Gibson introduced the serialization method that we primarily use to this day at Gibson USA, Gibson Acoustic, and the Gibson Custom facility in Memphis, TN.


The serial number will be an 8 digit number impressed into the back of the headstock with "MADE IN USA" below.


The pattern is as follows:


YY is the production year

DDD is the day of the year

RRR is the factory ranking/plant designation number.

Prior to 1984 when the Kalamazoo, MI factory was closed, the numbers 001-499 indicated Kalamazoo production. Ranking numbers 500-999 continued to indicate Nashville production through 1989.


Since 1989, all Gibson acoustics are built in Bozeman, MT and all Gibson electrics are built in Nashville or Memphis. Ranking numbers for Bozeman start each day at 001 and the electrics may start as low as the 300s.


Examples: 70108276 means the instrument was produced on Jan. 10, 1978, in Kalamazoo and was the 276th instrument stamped that day.


82765501 means the instrument was produced on Oct. 3, 1985, in Nashville and was the 1st instrument stamped that day.


NOTE - Gibson USA goes to a 9 digit serial number in early July 2005..

The sixth number is now a batch number- batch 0 starts at the beginning of the day, and once we stamp 699, the batch number will change to 1. The first 5 numbers remain the same, the last 3 numbers will remain the same. The only difference is the addition of this batch indicator.


There are always exceptions to these rules, the two listed below are worth noting:


Les Paul Classic: This model features an ink stamped serial number with no "MADE IN USA" (just as we used on the original 1952-1960 Les Pauls). Most will be 5 to 6 digits in length, but the earliest examples feature 4 digit serial numbers. There should be a space after the 1st digit with the 4 and 5 digit serial numbers, and no space with the 6 digit numbers.


The 1st digit indicates the year of manufacture for the 4 & 5 digit serial numbers, these were used from 1989-1999. The 1st and 2nd indicate the year of manufacture for the 6 digit serial numbers which we've been using since 2000.


Examples -

9 xxx = 1989 (4 digit number beginning with "9" used only in 1989)

0 xxxx = 1990

9 xxxx = 1999

00xxxx = 2000

05xxxx = 2005


Those beginning with "94":

In 1994, Gibson's Centennial year, many instruments have a serial number that begins with "94" for the year, with the remaining 6 digits indicating the ranking number."

Uhh saw this at the web site... but what am I missing?


Kinda confusing... I need to read this a little more carefully....


Still don't know the year of this serial number.




I'm going to read it carefully a few more times..


But read it about 5 times.... then looked at my number... still not sure of the date....


Oh Well .. it was a gift and I love it ...


But can someone interpet that stuff and tell me from my number the year this guitar was made???

Your serial number number is:



The first and fifth digits are the year: 90963566= "93", or 1993.

There are 365 days in a year, the second, third and fourth digits are the day of the year: 90963566= 096, or April 6th, the 96th day of 1993.

566 is the lot number Gibson uses to calculate the number of instruments produced that day.
