ALOT of "1979" Strats with S9 serial numbers I've recently seen online appear to be from 1980, including the Strat I bought.Body and Neck: All bodies are Ash, and usually a heavy piece.Pickup Codes: OOWWYY Example: 202378 - It is believed the first two digits are an operator designation for the person operating the pickup winder, this according to Abigail Ybarra herself.
Most Natural and Sunburts finished guitars seem to be three-piece bodies, painted ones may be more.
Necks are Maple, and are constructed from one complete piece if they have a Maple fingerboard.
In this case it stands for the 3rd week of 1980 and was a Thursday.
Ignore all the "FRR" stamps you'll find on the neck base and in the neck pocket.
Be aware of another code found on these pots, 013446.
