While this neck dating is useful in roughly determining the age of a guitar, it is certainly not definitive.
The neck date simply refers to the date that the individual component was produced.
Most notably, production dates have been penciled or stamped on the butt end of the heel of the neck of most guitars and basses.
MADE FENDER STRINGED INSTRUMENT For the majority of Fender's U. instrument production history, production dates have been applied to various components.
While there have been periods where dramatic changes have occurred, for example: the transition periods between Leo's Fender and the CBS years, as well as the transition between CBS' Fender and the current ownership, generally speaking, most models are feature specific and do not change from year to year.
Die Gitarre (griechisch κιθάρα, ursprünglich die Kithara, ein leierartiges Instrument) ist ein Musikinstrument aus der Familie der Kastenhalslauten, hinsichtlich der Tonerzeugung ein Saiteninstrument, von der Spieltechnik her ein Zupfinstrument.
( Lesenswerter Artikel) The guitar is a musical instrument with ancient roots that is used in a wide variety of musical styles.
Serial numbers are also helpful in determining the year of production of a given instrument.
Given the modular nature of Fender's production techniques, an individual neck may have been produced in a given year, placed in the manufacturing warehouse and remained in stock for a period of time, and then subsequently paired with a body to create a complete guitar in the following year.
So, obviously a neck date, while being helpful in providing a date range of production, it cannot be a definitive reference.
