The most effective analog tone control type EQ is the Manley Pultecs. It's not a full parametric design, but it is very easy to use, sounds wonderful and settings are quickly arrived at (a big consideration with EQ devices). The Weiss and Massenburg units have tremendous reputations, but are definitely overkill as tone controls.
The Z-System units are very good, but I would recommend the Tact room correction units. In addition to the room correction equalization they also come equipped with a 12 band parametric EQ. The problem with the Tact is that if you use the RCS feature it has a very steep learning curve. The upside is that it's extremely powerful in transparently changing the sound of your system in your room. It comes equipped with a calibrated measurement microphone and can be used (with a computer) as a powerful analytical tool. The 12 band parametric can also be used without engaging the RCS features.
The best way to actually learn how to use an EQ device is to simple play with and see how it sounds. It's an eye opening experience.
