When I did this a couple years ago, this was the combination that made a 500K vol sound like a 500K/500K.
223 + color + color. You can probably look up with the color bands mean, I would have to go back and find the bags.
It worked great but when I took the guitar out of storage, the output on the guitar was erratic so I ripped it out. One of the resistors may have failed. Don't have my multimeter or the inclination to figure out what happened.
( I can see now I had just twisted them together to test. I think the problem was I didn't solder them and it never got past prototype. But it did sound just like a 500/500. Better than a single 250K which was a bit darker.)
I literally forgot how I did this two years ago.
