passive equalizers


i am considering an equalizer, but i am looking for a passive, preferably graphic equalizer.

has anyone heard of any decent passive equalizers ?? if so, what brands ??

i prefer a graphic because it is easier to operate, but considering white instruments manufactured a parametric which was supposed to be pretty good, i would consider a parametric. any ideas ??
the dbx 20/20 was the best eq ive ever used,easy to use & it has lots of great features,as far as eq's go your not going to find a more (high end) eq without taking out a loan for an accuphase or a rives.
Graphics may be easier to to operate, but they aren't as useful as a parametric with hi and lo filters. You should take a look at the Manley Massive Passive.
