I use it for bass and bass drum tracks. I usually put a high shelf EQ somewhere about 350Hz to 500Hz variably cutting from about 6db to 12 or so, and I find that most EQ's color the sound in a way I don't like. I find The LP-64 does it best, without coloration.

Both of these are FabFilter vids (I don't own any FabFilter stuff at this time).
This one walks through some mix choices that are interesting.

This one talks about the ringing etc between LP and regular eqs...

This last one was the one I meant to post in the first place. I didn't actually watch the FF Video on basics I posted above before posting it. I didn't realize there were 3.
 
and BTW, that mid-side stuff where he cuts the freq in the Mids and boosts in the side seems like hooey to me if it's only a stereo mix. Idk. Just my 2 cents. It could be really complicated where it only boosts that freq where the two sides differ, but if it's a mono track ??? What on earth does that mean? so... take it with a grain of salt. You can download and play with it, but I think the mid-side thing should be viewed with healthy skepticism not - 'oh I gotta have that!'

This was very informative - thanks very much.
I have not tried the multiple Sonitus idea for the brickwall effect - that is a great idea.
I also need to use the ProChannel more.
Best,

I am very curious to know what software eq Mr. Anderton loves.

 
The ProChannel is my go-to EQ because 1) it works as expected and doesn't mess with the sound, 2) the four different curves are very useful (especially on acoustic guitar), and 3) it has high and low pass filters to -48 dB.
 
But my EQ needs are pretty modest. High shelf/low cut on voice to compensate for using a dynamic mic, a little 3.5 kHz on the drums sometimes to make the snare "crack," high shelf on the bass to bring out pick sounds and on synth bass for accenting transients. Amp sims have their own tone controls, so I'm covered there. The rest is cutting in strategic places, for example, taking out a little 300-400 Hz on some instruments. Most synth sounds are fine the way they are. I do like the Blue Tubes Pultec; actually I'm a fan of any Pultec if done right. And I  use the Sonitus when I need multiple high or low pass stages in series to obtain extreme, brickwall-like responses. 
 
Sorry for the boring reply, but I'm not much of a "cork-sniffer" when it comes to EQ. Usually I just need a tweak here and there, so I don't place a lot of demands on them.

I've found that it's excellent for dealing with drum overheads recorded in sub-optimal rooms. You can do quite a lot of narrow notching of bands fairly close together, without killing the sound like a regular eq would.
