Dating a gretsch guitar
Gretsch used several different serial number schemes through the years.Each of them can be used to accurately pinpoint the age of a guitar, if you have the correct information.In the beginning, Gretsch simply wrote serial numbers inside the guitar in pencil.
Serial numbers on Korean made guitars in this era were printed on a sticker affixed to the back of the headstock.On hollowbodies, the label is usually visible through the f-hole.On other models such as solidbodies, it should be inside a control cavity.For example, 27136 should be February (2), 1967 (7) and the 136th instrument made that month. (i.e., 1974 would be 4) Last 3 digits = number of the instrument.A hyphenated number was embossed on the back of headstock. For example, 3-8094 would be March (3), 1978 (8) and the 94th guitar made that month. The next three digits are the model number, without the 6 at the beginning.
