Out of curiosity, are you hearing more finger-sliding-across-strings noise? At my gig last night, it seemed a bit excessive, so I had to CUT frequencies around 1kHz. That seemed to help.
With good technique, you should not have any problem with string noise. I have a sizzly wizzly tone, and have zero issue (although I do like to cut around 800 hz just to take a bit of the gank out of the tone, but it has nothing to do with string noise).
I gig with tweeters a blarin' and brand new stainless steel roundwounds on aggressive 70's style J basses with my passive tone control wide open.
IMO, don't try to fix 'string noise' with EQ. Go to the woodshed, and you will be happy you did down the road. Per Chef's post, if you want to 'cheat' a little bit, use nickel rounds or flats versus stainless steel rounds. If you already are using nickels or flats.... get ye to the woodshed!
IMO!
