Sculpting! Awesome! And you are still getting some extra noise?
My best guess is that it would be that the EQ pedal is designed to give about a 1db boost to the overall signal with the sliders flat when engaged.
I don't know why they do it but my best guess is that is what you are hearing.
It's good enough for me with that so I won't change it by my opinion is that you are getting the best that you can out of your pedal.
The new, higher quality opamps should and sounds like did reduce the problem. Best guess is that what you are hearing is that initial boost.
Maybe try dropping all the sliders a notch and see if it disappears?
Or try dropping the output slider a notch and see.
Maybe you can eliminate it by eliminating the initial boost back to unity gain.
