OK, let's clear some things up:
1) The OP may be referring to a .022 microfarad capacitor, which is a standard guitar capacitor, not bass.
2) As stated above, many basses use a .047 microfarad capacitor, which is a standard bass capacitor for conventional passive tone circuits
3) The frequency inverse to value is right on. I prefer a .033 capacitor, especially if there is only one tone control or on a bridge pickup tone control, in order to flavor the upper mids a little more.
4) The CTS 250kohm pots are standard for most standard (not overwound) bass pickups that measure @ 12kohm or less DC resistance at the leads.
If it turns out to have a .022 guitar capacitor, you can:
1) play it the way it is, if you like it;
2) change the cap completely; starting with a .047 as a conventional starting point for further experimentation; or
3) add another capcitor in parallel to fine tune your tone, anything from a .01 to a .1, depending on how much highs you want to roll off.
There are those aficionados who swear the different type or manufacture of capacitor makes a difference; orange drops, bumble bees, etc. I have never been able to hear a difference in the brand or make (ceramic, paper, mylar, etc.), with the only caveat is that all capacitors are inherently unstable and will deteriorate over time, whereas pots are very stable if taken care of.
Yeah, probably more info than needed to know....
