It may come as a surprise, but the serial number on the back of your Gibson Les Paul says quite a bit about where and when the guitar was made. The Les Paul, one of the most popular guitar models in history, has been through many different evolutions and updates. Depending on the model type and year a specific Les Paul was made, certain nuances of the guitar's serial number may be different. See the guide below to determine what your Les Paul's serial number means.
Gibson's systematic serial number process for the Les Paul began in 1975. You can tell specifically which of those three years a given Les Paul was made in by looking at the first two digits. The production year 1975 is indicated by a 99 at the front, 1976 is a 00, and 1977 is a 06.After that comes 6 more digits. And, unfortunately for the curious 1975-1977 Les Paul owner, they do not have any more information about where or when the guitar was made. Assigning arbitrary numbers, though, would soon be stamped out by Gibson.
In 1977, Gibson changed the way their Les Paul serial number worked. Instead of using the first two digits to indicate the year, they spaced them out to surround a three digit day number on both sides. The serial number still had eight digits, but they all received a specific meaning. The pattern went as follows: (year's first digit)(day number digit)(day number digit)(day number digit)(year's second digit)(factory number digit)(factory number digit)(factory number digit) At the time, Gibson had two major plants that manufactured Les Pauls in the United States. Any guitar with a serial number whose last three digits are between 001 and 499 was made in Kalamazoo, Michigan. If they are 500 or higher, then it was made in Memphis, Tennessee. So, if a Les Paul that was made between 1977 and 1984 has a serial number of 83655501, it was made on December 31, 1985, in Nashville. This method has since become the basic standard for numbering most Les Pauls. Gibson owners support it enthusiastically because the system makes it easy to identify when and where their guitar was made, plus, the numbering process has a certain tradition to it which is very much in line with Gibson's storied history.
In 1984, Gibson decided to close the Kalamazoo, Michigan plant. For a period of five years, Nashville was the only place that produced Les Pauls. Then, in 1989, they shuffled their plants' duties. Since that year, all Les Pauls have been crafted in either Nashville or Memphis. The system they adopted at that time remains pretty much intact today. With the altered system, the last three digits on a Les Paul serial number start in the 300's. From there, they go up by one for each guitar that comes off the line. An example of this would be a Les Paul with the serial number 83659301. It means that the guitar was made on December 31, 1985, and was the first one to be finished that day.
In 2005 Gibson again altered their system. It is a slight change that makes the serial number on guitars made in the last 5 years 9 digits long instead of 8.They added a number, now in the sixth position, that indicates the "batch" number. Depending on how many Les Pauls the factory produces in a given day, the batch number will range from 1 to 9. So, for instance, if your Les Paul has a serial number of 003085310, it was made on January 30, 2008, and was the tenth guitar made in the 5th batch of the day. The addition of the batch number helps to provide a more detailed picture painted for each Les Paul by the serial number, as the production of guitars has risen quite a bit in the last 30 years.
Every serial number rule has its exceptions. This is especially true for the Les Paul line, because there are a wide variety of specialty models within the line itself. Les Paul Classic models, made to recreate every nuance of the original Les Pauls created between 1952 and 1960, feature serial numbers with 4, 5, or 6 digits, depending on the decade they were manufactured in. Les Paul Classics made in the '80s have four, ones from the '90s have five, and ones from the 00's have six. There will be a space between the first digit, which indicates the specific year number, and the rest on the serial numbers with 4 and 5 digits. On the Classics stamped with six digits, the space won't be there.
In 1994, Gibson used special serial numbers on their guitars to commemorate the company's 100th anniversary. All Les Pauls made in 1994 have a serial number that begins with, you guessed it, 94. The other six digits tell you the ranking number. If a Les Paul has a serial number of 94000300, for example, it means that it was the 300th one produced by Gibson in 1994.
The Gibson Custom Shop produces all sorts of specialty instruments. They make reissues that copy Les Pauls from a certain era, guitars made with special materials, and guitars that are modeled after ones that famous musicians play.
The 1952-1960 Les Paul reissue, made by Gibson since 1992, is designated by a serial number with the following pattern: (Model year the guitar is copied after)(year of production)(ranking number first digit)(ranking number second digit)(ranking number third digit) The 1961-1969 reissues, meanwhile, have six digit serial numbers that follow a different pattern. It is as follows: (Production year first digit)(production year second digit)(ranking number first digit)(ranking number second digit)(ranking number third digit)(8) Standard Custom Shop Les Pauls have their own serial number sequences as well. Their sequence is: (CS-standing for custom shop-)(production year digit)(ranking number digit)(ranking number digit)(ranking number digit). A Custom shop Les Paul with the serial number CS30333 means it was the 333rd of that line produced in 2003.
Signature model Les Pauls are produced to mimic those of famous musicians. The most popular ones are modeled after the guitars of Ace Frehely, Dickey Betts, Gary Rossington, Jimmy Page, Joe Perry, Pete Townshend, Peter Frampton, Slash, and Zakk Wylde. The list below shows how each is stamped. Note that the parentheses are digits in a ranking number for each specific model: Ace Frehely: ACE()()(), Dickey Betts: DB()()(), Dickey Betts Red Top: DBR()()(), Gary Rossington: GR()()(), Jimmy Page aged model: Hand signed by Jimmy Page, no serial number, Jimmy Page aged model 2: PAGE()()(), Pete Townshend Deluxe: PETE()()(), Peter Frampton Custom: PF()()(), Peter Frampton LP Special: PFY()()(), Slash cranberry finish: SL()()(), Slash regular finish: SL()()(), Zakk Wylde: ZW()()().
As you can see, the serial number on the back of your Les Paul is more than just an arbitrary sequence. Gibson uses an array of constantly evolving serial numbers to label their Les Pauls. Each new addition is an improvement on the last, and can tell you quite a bit of interesting information about the guitar it’s stamped on. The serial number is much like a birth certificate for each individual instrument. So, if you get a chance, check out the sequence on the back of its headstock the next time you pick it up.
