Fender precision bass dating serial numner
So starting in mid-1976 the serial number was moved to a decal on the peghead.
Even with the new system, Fender didn’t like to throw away a perfectly good serialized decal just because the year code would be incorrect.
though most collectors will value all 1965 Fenders similarly to Pre-CBS (the sale was consummated in early February, 1965) 100000 to 110000 = late 1965 110000 to 200000 = 1966 180000 to 210000 = 1967 210000 to 250000 = 1968 250000 to 280000 = 1969 280000 to 300000 = 1970 300000 to 330000 = 1971 330000 to 370000 = 1972 370000 to 520000 = 1973 500000 to 580000 = 1974 580000 to 690000 = 1975 690000 to 750000 = 1976For many reasons, Fender decided to change the serial numbering system and it’s location in the mid-1970’s.
You can imagine that it might have been cheaper to have the serial numbers added to the decals rather than have them machined.
The serial number can only generalized the age of the instrument within a few years.
In mid-1954 Fender changed the location of serial numbers to the neckplate. Because different companies did the stamping of the serial numbers on neckplates they vary in location and layout.
Unfortunately, there is also some overlap in serial numbers between years — again due to the fact that neckplates were re-ordered various times from various manufacturers.
Dating a Fender guitar with the serial number is a hit or miss propisition.
It helps narrow things down, but in most cases is an inexact science.
So, they ordered neckplates that were supposed to have numbers above 100,000.
But the stamper misread the order and thought that the number “1” was an “L” and so instead of plates starting with 100,000 they started with L00,000. But it took a while to manufacture and number the plates.
