While there have been periods of dramatic change—such as the transition periods between the Leo Fender years and the CBS years or the transition between the CBS years and the current ownership—most models are generally feature-specific and do not change from year to year.Serial numbers are also helpful in determining an instrument’s production year.Japanese-built Takamine Pro Series guitars can be reliably dated from the eight-digit serial numbers typically found at the neck block inside the instruments.The first two digits designate the year of manufacture, followed by two digits denoting the month.The remaining four digits denote the instrument’s sequential number of manufacture among all the instruments made during the month indicated.For example, serial number 07100091 indicates a guitar built in 2007 (07), in October of that year (10), and that it was the 91st guitar made that month (0091).
The following chart, however, details the best information we have for the approximate last serial numbers produced in each given year before 1960.
This third iteration of the label had “Fred Gretsch Mfg. and serial No., and it said “That Great Gretsch Sound” at the bottom. The 5-digit numbers on these labels always begin with 1 or 2 and are sequential, do not follow the “date-coded” convention, and precise dates cannot be determined using the serial numbers.
