I recently upgraded my guitar with Seymour Duncan '59's. The guy I got the pups from told me I should upgrade to 500k pots. When I swapped out the pups, I noticed the pots with 500k, as well as 480k stamped on the back of the pots.

Would these be original, or are they upgraded from a previous owner? The jack plate is nickel plated, not plastic, and I put on Gibson Top hat knobs on the pot shafts with no problems or forcing them on. From what I have read, you can't put Gibson knobs on an Epi without issues.

I don't know, I would need to see photos. I've used a lot of CTS and Bourns pots but I've never seen a 500K pot with a slightly lesser value stamped on it. If the American made knobs slipped right on, it sounds like CTS though. Have you checked the output with a meter per chance? Epiphone stock pots these day are marked B500K on volume and A500K on tone. The difference is the "B" pots are Linear Taper. :hmm:

Some pots if they have some kind of serial or part number you can actually google the #, and it should come up with the maker, and specs of the pot...sometimes works with caps aswell... i was curious about the pots in my newest guitar, so i tried it and worked for me...hope it works for you if you try it....

good info as always, SJM! I noticed the A and B on my 98 when I did the 50s wiring, but didn't know what they meant :applause:
