difference between 250k and 500k pots

    i'm putting stacked pots in my j-bass but the only ones i can find are 500k what sonic difference will this make over the standard 250k pots?
  2. What is a Potentiometer and How does it work?

    You can use any value you like, but a 250K will give a slightly warmer tone than a 500K pot. The 250K pot bleeds off (attenuates) some of the high frequencies to ground. A 1Meg-ohm pot will attenuate even less than a 500K pot, so if you want to hear your guitar "wide open" you may want to try one.

  3. So does that mean that the higher the pot number, the more tonal options that are available, especially on the high end?

    You could look at it that way. With the 500K pot, you'll be getting more of the original pickup signal without any of the attenuation you'd get with a 250K pot.

    If you have a 500k pot and roll the knob back a bit would it equal a wide-open 250k pot?

    Not completely. A 500k pot has a total of 500k ohms between the pickup and ground, the 250k will always have 250k, regardless of the position of the wiper.

    And what about linear and audio, is there any difference other than the ratio?

    pots are pots are pots. They don't have any effect on tone by themselves. It's their relationship with the capacitor that effects the tone.
