Return to the Main Index. Sometimes there just isn’t enough information on electric instruments and amps to allow them to be properely dated. And many people ask me to try and determine the year of their old amplifier, or to help them with the year of their older off-brand electric guitar. Since I primarily collect amps by Fender, and guitars by Gibson, Fender, Martin, National, Epiphone, Gretsch and Rickenbacker, I really can’t help them with these other less popular brands.
As you have probably noticed, there is plenty of information here to help date the brands that I am interested in. But where does that leave everyone else? Well I’m not one to leave you out in the informational cold, so here’s something that I use quite often in dating amplifiers and electric guitars. It’s called the “source-date code”, and it can help determine the approximate age of an electric instrument by the date its components were manufactured.

Rare “stell adjustable neck” teisco gen gakki hollow body AncientSociety An early s pot from a Gibson guitar. Once decoded, the writing on the back or sides can be very informative If you’ve been reading articles about dating a vintage guitar, you may well have come across mention of pot codes. The pots, or potentiometers to give their full name, are the variable resistors that control volume and tone. Better quality pots are often stamped with a number of codes; typically part numbers, date of production, manufacturers codes and resistance values.
Many pots don’t carry all of this information, but the better quality guitars produced in America regularly do. So where are these codes? Normally they are stamped or inked onto the back or sides of the pot. So reading them will require opening control cavities, removing scratchplates, or in the case of a semi acoustic, removing the pots entirely. Codes can be worn, obscurred by solder and other components, or simply very small. Finding them is not always easy; this is obviously not something for the faint-hearted, but once performed a few times, nowhere near as daunting as it might at first seem.
