Digital emulations of well-known analog equalisers

SSL ever doing that - they went for the best technical specs they could
have.
Agreed. Some types of distortion can sound nice on the right material,
but I prefer to add that separately if I think it's required. I don't
want an EQ to make that decision for me.
Not that all equalisers are equal, far from it. Some
of those classic
designs had some unusual features such as higher order shelf filters
which are actually quite nice to have.
I wrote an equaliser having those some years ago (not yet published,
maybe I will some day), and it has become my 'workhorse'. You can
see some of the frequency responses here:

Please do consider releasing that if you get time. I can think of several
situations where it would have been very useful to have that :-)
