This means that the the serial numbers starting in 1994 ran consecutively on both the MIJ and the CIJ models while the MIJ logo was being phased out.
Mid–1997 the CIJ logo was the only one used on Fender guitars coming out of Japan (with exception the Squire series). I really don’t know, but the MIJ logo Fenders were for the USA market.
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.
Unlike the auto industry which has specific model years for their products, most specifications for a given Fender instrument model, change little if any, through the lifetime of the model.
So, obviously a neck date, while being helpful in providing a date range of production, it cannot be a definitive reference. The list goes on and each is an icon in its own right.and both were being made at the same time from 1994 till 1997.The numbers for each year typically overlap, as there is always a transitional period between successive years and as necks and complete instruments that were made and serial numbered late in any given year were used on instruments assembled and sold in the early months of the subsequent year.As always, dating by serial number is not an exact science and is seldom definitive.
