Initially my question was 250KOhm or 500KOhm but I found the info pretty easy.  Rather than a specific question here I'm hoping for some fill in the blanks type of discussion, since I am missing a lot of information and not just some single point.

My current build is a 4 stringer using a single humbucker and a fender style bridge.  I've noticed a banjo like quality on my previous builds and I'm thinking that I will use a 250KOhm volume pot for a warmer sound.

I've notice some comment that tone controls are underwhelming or a waste of effort on a cbg or where there isn't a preamp.  Is that a general concensus?

 I have read that the tone pot needs a capacitor.  Is that ony if you are using an audio taper pot for the tone? Gitty sells a 10KOhm linear taper pot for a tone control but doesn't sell capacitors, so is there an implication there that a capacitor isn't needed on this kind of pot?  And the low number 10KOhm linear taper vs 250 or 500 on the audio taper would still indicate that more highs would be bled off to ground?

I'm wanting to err in favor of warm and also don't want to short change this instrument if a tone pot is a plus and not just another knob.
