Welcome to the forum. Dating the festival series can get a bit tricky. Washburn has used a couple different serial number systems and the festival series has lots of exceptions to the rule. Here is some general info on the EA40.
- single sharp cutaway dreadnought style, mahogany top, oval soundhole, bound body, abalone purfling/rosette, mahogany back/sides/neck, 21-fret bound rosewood fingerboard, rosewood bridge with pearl dot black pins, three-per-side chrome diecast tuners, Washburn 3200/Equis II preamp system, available in Black, Natural, Tobacco Sunburst, White, or Wine Red finish, mfg. 1979-1991.
Grading 100% Excellent Average
N/A $500 - 575 $325 - 375
Last MSR was $1,000.
In the mid-1980s, a spruce top replaced the mahogany top. Circa 1987, EQ300 electronics were introduced (sliders instead of knobs). By 1990, Equis II electronics were being used. This model had birdseye maple back/sides with Natural finish as an option.
Either the first 2 digits, or the first digit, are typically used to identify the year of manufacture.
For example, 8901827 indicate the instrument was made in 1989, 1988, or 1998.
Instruments with serial numbers that have 5 or more characters are from the late 1980's-2000's
Instruments with serial numbers that have 5 characters or less are typically from the 1980's.
Instruments with serial numbers that have 4 characters are from the 1970's and early 1980's.
For instruments produced after 2010, usually the first 4 digits can indicate the year of manufacture.
There is no serial number information or tracking capability for pre-1978 models.
If the instrument does not have a serial number, it is likely a factory prototype or sample, and it is impossible to gauge its exact age.
So, with a first digit of "9" your guitar could be a 1989, not a 1994 (first two digits). But, based on the above data the birds eye maple back and sides did not start until 1990 and production ended in 1991. If I had to bet, and I would not bet a lot, I'd lay a few pennies on a build date of '89, late in the year. Just as teh transition to birds eye was happening. The second set of numbers is likely a factory mark that does not mean anything in terms of build date, etc..
Finally the guitar has a solid wood top and laminate back and sides.
