Gibson guitar pot dating
Stamped on every potentiometer (volume and tone pots) is a six- or seven-digit source code that tells who made the pot, as well as the week and the year.
The source dating code is an element of standardization that is administered by the Electronics Industries Alliance (EIA).
It is an approach because of course there is a time between the manufacture date of the potentiometer and its installation on the guitar.
This is also a method for lesser known brands without a serial number about the production date.
On the potentiometer is a code that gives information about the manufacturer and the year and week when it is made.
Where to find the code Stamped or punched you can see a six- or seven-digit source code on the back or side of the potentiometer.
Hfner Hfner guitars from before 1971 often do not have a serial number.Assuming that the pots are original and therefore have not been replaced.The source code on pots indicates the manufacturer and date when they are made.If the pot is an original, it indicates a date before which the guitar could not have been built – so it’s always a good idea to have extra reference material around.Finally, a word of caution: This method applies only to American made pots and not all potentiometer manufacturers subscribed to the EIA source code date.
