    Unless there's a "137" stamped somewhere before the "8446" (some manufacturers pre-stamp the manufacturer code, can be faint), then it's not an EIA code you're looking at. Is that every single character on the pot casing that you've listed?

    EIA markings are are not mandatory, and were never fully standardized. Those numbers sound like a familiar format, and it's possible that CTS dropped their "137" manufacturer code at that time in favor of simply "CTS". If you know the guitar is from the 80's anyway, it may be reasonable to assume that it's 1984 / 48th week (though I'm not certain here). CTS pots made for Gibson for example, dropped the standard EIA code some time ago (I don't recall what dates or era off the top of my head) and were instead marked with Gibson's part number. If CTS was making parts for a particular manufacturer, they may have simply stamped whatever number system the purchaser requested.

    That seems reasonable . The guitar is a Schecter Strat type , and I took those numbers from the volume pot . The guitar has a master tone pot which is a push-pull type to tap the coils . That pot only reads 470k.
