I have a new Squire Jazz I'm doing some modifications to. The bass only has a volume pot, 500k and no tone pot. (Chris Aiken model). This thing is beyond bright with only a 500k volume pot. Anyhow, I have a new 250k pot and 47uf cap and was thinking about using it for the tone. I'm assuming the 250k tone pot would just roll the brightness off a bit more than a matching 500k. Therefore, keeping the 500k volume pot will maintain a bit more brightness than using 250k pots for both. Am I missing something here, not quite sure?
