I'm not sure how all different guitarists use tone pots, but I like how you can roll it real low with a .047 uF and get a smooth fuzz distortion or a super dark jazz tone. Putting in a .0015 or so uF cap would successfully snip of the piercing highs, but then you'd lose the typical tone knob ability to go really muffled.
I wonder if by quicker you mean take just the top end off before eating up all the mids. Something to understand about cap values and tone knobs that might help, or might not, sorry if you already know this, is that the cap value decides the frequency cut off point of the tone control, and the pot changes the amplitude of frequencies beyond that point, so if you have a .047 uF cap and you turn down the tone knob just a little, it doesn't start out by taking the highest frequencies first, it takes everything beyond that frequency all at once, to varying degrees as you turn the tone knob. So if you just want eliminate that annoying tip top and keep everything else intact, you have to use a cap value that's low, between .0015 and 400 pF. With my veratone type control, I can make Texas Specials sound nice by applying the .0015 uF cap and putting the 500k audio tapper tone control to about half way.
