Talking Gibson's Serial Numbers

Hello Sunburst. According to my edition(7th) of the Acoustic Blue Book, here is the scoop on your serial number. "In 1977, Gibson first introduced the serialization method that is in practice today. This updated system utilizes an impressed eight digit numbering scheme that covers both serializing and dating functions. The pattern is as follow: YDDDYPPP. YY is the production year; DDD is the day of the year; PPP is the plant designation and/or instrument rank." I assume the day of the year is the Julian calendar date which of course is 1 - 365/366. According to the Blue Book 001-499 show Kalamazoo production, 500-999 show Nashville production. The Kalamazoo numbers were discontinued in 1984. When acoustic production began in Bozeman (in 1989) the numbers were reorganized. Bozeman instruments began using 001-299 and 1990, Nashville began using 300-999.

Hope this helps and doesn't just confuse you. Enjoy your Gibson.
