tone controls

OK, so my Pbass has passed muster and is defintiely sound enough to play out...holds tuning very well and has good action, and has never cut out on me. My question is this: For most of the music I play in the bands in which I use this bass, I virtually NEVER wind the tone control up past 5. Now, while I can probaly live comfortably with that for many years, I wonder about the controls...I 'understand' that passive basses are "cut only", that is turning something down removes part of the tone. Is there a way to change the wiring...eg, different value pots or caps...that will allow me to run the tone control closer to 'flat out' more of the time, and maybe allow me to have better control over the portion I do use most? Is it really a no-win situation, I'm just giving up potential tone from the latter half of the sweep just for a bit more convenience in the lower half? Will bigger caps let more bass through?

Whaddaya say, folks, any thoughts or tips?

I had a Jazz Bass wiring set-up made with a variable tone control that worked really well. You can find one for a P Bass here (http://bit.ly/b7Uy0H). I had it built and shipped to me and it was well-worth the $.

I leave my controls "wide open" and get my "tone" off the amp.
My P bass sounds best this way, to me anyway.
I find Precisions to be quite "bassy", generally speaking.
There's many ways to shape/modify your tone.
Pedals, strings, EQs, pickups, mods, ect.
A moderately powerful amp helps a lot, too.
Generally, the more power, the more EQ-ability, IMO.

The bigger the cap, the more the cut ...

Your P bass has a 47 or 50 nF cap.
Maybe a 68 nF ...

You can try it with a 22 nF cap.
That's the value of Fender Jazz Basses in the 1970s.
The Fender Precisions always had 50 nF.
A 22 nF might solve your problem.
