These ary widely in quality. Some are no better than the old "graphic equalizer" boxes. Terrible.
The best of these IMO, is the EQ that comes with full Amarra player software. This only runs on Mac, but its is totally transparent. I could not have gotten best of show at RMAF from TAS in 2009 without it:

There are three filters that you can set amplitude, Q and frequency on.
