Pots questions

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.

Hi Carlotte,

The best overview of pots I have found is on the right hand side here http://www.axesrus.com/axeElectronicsPots.htm

I hope it is as good when they cover tone pots.

To convert a pot to a tone pot you just add a capacitor - different caps give different amounts of treble bleed to earth through the pot again a good overview is here (it also covers pots but I find the previous link the most informative) http://www.guitarelectronics.com/category/wiring_resources_guitar_w...

Usually I keep the tone pot value the same as the the one for volume so don't know what using a 10Kohm tone would do. Regarding getting the best out of a piezo I answered another thread with some info on this here

Excellent! Thank you so much! I got a lot out of your links and have enough information to choose my capacitors! I think I can proceed now.
