Because my tone pot was working strange i took a closer look at the electronics of my Matt Heafy 6 string Epiphone guitar and i was very surprised to find that the Shadow Killpot they are using for ACTIVE EMG 81/85 pickups is 500kOhm with 2A223J capacitor. Am i missing something how this killpots work, is this normal or it's an Epiphone mistake and this killpot have to be replaced with 25kOhm killpot?
