0.022uF >> brighter
0.047uF >> rounder
500k pot >> brighter
250k pot >> rounder
high output >> rounder tone
lower output >> brighter tone
vintage wound single coils are lower output; therefore brighter >> needs a 250k pot + 0.047uF cap to tame the brightness.
humbuckers are higher output; therefore rounder >> needs a 500k pot + 0.022uF to offset the roundness.
Overwound single coils would behave like humbuckers (but with hum of course, unless noiseless), so I'd treat them the same way: 500k pot + 0.022uF cap.
Fender SSH strats I think use 250k + 0.047uF, because anything else would make the SC's too bright.
AFAIK many asian SSH guitars (Squier, Ibanez, Ibanez GIO) use 500k + 0.022uF. Stock pickups are usually a bit on the overwound side.
What guitar is it and what pickups are you using?
