1963 Gibson ES 345

Recommended Posts

Hi All,

 I am trying to identify a potentiometer date code on a 1963 Gibson ES 345. I can not find a manufacturer for these pots. All have the same code and I believe them to be original.  They do not have a code number like 134/137.

Thanks Bob

welcome to the forum. I think it might be worth your while contacting Charlie Gelber, who is something of an expert on early Gibson ES guitars, if he can't answer your question know one can.

Here's his website:



Good luck

I can only guess the decode:

A type taper, 500K=500,000 OHMs, 98 year, 44th week. I could not find the manufacturer's EIA code.

The pots in the sixties should be stamped embossed that I've seen. Also, each pot was enclosed in a metal shield. So I'm not sure if it is the original pots.
