For more treble. And a bigger treble cut.
Go and buy.
1) A Fender No Load Tone Pot
2) A nice 1meg pot for your volume.
You're done.
The Fender NLTP is a 250k pot that comes with a larger (can't rem value) cap meant for single coils. So it will cut treble faster esp in the case of humbuckers. Also, you can turn the pot on full and it will be bypassed, taken out of the circuit, so you have bascially, no tone pot when at 10.
The 1 meg pot for your vol is to further reduce the load on your circuit when your pot is on full. Its like there's no load there.
The higher the pot value, the more load it has on your circuit when its full on. The larger the cap in your tone pot, the faster it bleeds treble off.
Note that the vol/tone pots will function the same way.
