i suggestt doing a little research on graphic vs parametric EQs on the net. that topic can drag on and on and can get rather tedious for those of us that are more into the art of production then the science of electronics.
a SUPER basic overview is that graphic EQs are fixed frequency with fixed Q or bandwidth.
parametric EQs (per band) are frequency adjustable (depending on the make and model) and Q or bandwidth adjustable (again depending)
i'd imagine you are looking for a parametric EQ
analog can m ean two different things
if you are looking for more of an old analog synth type sound, i'd recommend the Moog 3 band parametric. they aren't easy to find, but they sound awesome. probably run you about 500 bucks.
if you are looking for a good EQ that's not based on analog synth type circuit design, then there are tons of units people here can suggest, i'd more then likely tell you to get something like API or great river, and those aren't cheap by a long shot.
