Other things to look for include chasses placed in cabinets from a different year, “doctored” tube charts, non-original control plates (usually reproductions) on silverface amps, original transformer bell ends (they have correct date codes, of course) on non-original transformers, and non-original knobs (either repro or silverface knobs on blackface amps).unusual things can be found such as the empty “Pulse Adjust” hole on the rear of early ’60 brown amps, the “middle” volume control, use of tweed style grill cloth, strange non-documented transitional circuits, and changes in tolex color including the super-rare cream colored “brown” tolex that is found on some late ’60 amps. Given that people may refer to this information seeking specific production quantities of amps they are curious about, it should be pointed out that the serial numbers apply to chassis types, and not specifically to amplifier models.
The serial numbers will start with a letter that corresponds to specific years of production. You will not find the MADE IN JAPAN stamp on the headstocks of Fender MIJ guitars. acronym for "CRAFTED IN JAPAN" These guitars were made from 1997 and are still being manufactured today.
From my experience, any serial number below V016000 denotes a guitar made at the fullerton plant (1982-1984).
Of course, there are exceptions to this generalization.
It would be more accurate to say that approx 650 of each of these models were produced in ’60.
and both were being made at the same time from 1994 till 1997.
These stamps can be found in differentlocations on your guitar, so now I'll tell you where you need to look to find these markings... acronym for "Japan Vintage" On these guitars you will find the letters "JV" stamped/engraved into the neck plate of the Stratocasters and bass guitars and on the bridges of the Telecasters and other guitar models.
