In the interest of understanding tone circuits...Perfect, thought it might be that!
To the ear, it might seem that using a large cap rolled back a tiny bit, is the same as a tiny cap rolled back more.
But if you look at it on a 'scope, and possibly if you wired both ways and switched between them, you'll see a difference.
Rolling back a little keeps a lot of 'dry' signal, but the signal that does get to the cap is heavily cut by the large cap. From highest audible highs, down to upper mids, and lower. It doesn't seem that way because we don't roll back very much, and most of the signal is untouched. But that's why it gets muddy so quickly if you roll back more.
Using a small cap, and rolling back more... there's less dry signal, but the signal that sees the cap is largely left intact. Just the highest highs are cut. Even pushing the entire signal through it, it won't be complete mud.
