Ive experimented with 250k/500k pots in all combinations in a P bass and J bass (including with quarter pounders). I found with 500k pots they didnt add treble or aggressiveness or clank but rather, just make the tone brittle, painful to the ears and made mids less accentuated.
With P basses, i actually dont mind one 500k for tone pots in P basses. But with my jazzes, even when i just changed one pot to 500k, i didnt overly like it.
Edit: I find quarter pounders (more so than other pickups) respond VERY much to the height that they are set at. Moving my SPB3s up a millimetre or two changed my tone drastically (more highs, more aggressive). And i thought they were already pretty high and aggressive before that.
