Need some help with pot values...

[Tor]

I have a Telecaster with a Fralin P92 humbucker in the neck and an OC Duff Plankster single coil in the bridge.

The switch and the pots make a lot of scratchy and ugly noises. Have tried to use contact cleaner, but to no avail. I figure I'll just swap out the switch/pots. However, I am very unsure of what the pot values actually are. There's a lot of solder on top, so I can't figure out if they are 250K / 500K. There's a cap on the tone pot, I don't really know anything about it, but it says ARCO 022m 50v. From this cryptic info, would anyone venture to take a guess at the pot values I should go for here? The schematic of the hot wire is as follows (volume pot in middle, tone on the bottom):

Just desolder the pots and measure them.

i cant see the codes on the pots, but measuring is always a good plan

Ah, I didn't think about that possibility... Thanks!

Not related to the post, but really cool seeing you around here again, Tor!

Have you tried Deoxit? Far superior to old style contact cleaners.

The pots are almost certainly 250K, and the tone cap is .022uF - we generally use a u in place of the Greek letter Mu, which looks like this: μ

Aw, kind of you to say, thanks!

eclecticsynergy, thanks for your input.

If all pots crackle, it could be also a defective amp or the first pedal. The first cap in an amp or the pedal should filter the DC out of the signal. This DC causes a static notice when turning the guitar pots.
