As I'm trying to learn how to EQ things properly, I stumbled across a cool article. Enjoy:

That is a very good article, indeed. I was especially gratified to read the preamble, before he actually dives into the frequencies, as this is the absolute best and most important information in there:
I learned a lot about equalization by sitting down with a graphic equalizer and lots of records. After about 30 hours of listening to the effect of different bands of equalization on the records, I began to "hear" the effect of certain frequencies on overall mixes.
...
Doing an exercise like this is the very beginning of training in using equalization. There are commercial CD packages which attempt to duplicate this type of test. They are no real substitute for switching the equalization on and off as the CD (or music source) plays.
The next step in the training is to apply specific equalization to specific instruments. Recommended or "key" frequencies are used and the equalization is switched on and off while soloing the instrument and then while listening to the instrument in the mix.
The point of this "ear" training is to gain the ability to hear what frequencies would be needed to bring up or down in a specific mixdown. Until one obtains the ability to "hear" frequency, one has only limited ability to use equalization.

Follow this advice for two weeks, and you'll be writing articles on how to EQ, and not reading them ;).

Indeed, unfortunately it's hard to find all that time while working and going to school...it may take longer than 2 weeks...but someday I'll get it!
 
There are lots of systems that split up the spectrum into different sized bands...the euros have bark and mel , we have 1/3 octaves.. like the man says though , it's nice to have maps , but if you really do the homework and repititions then you'll learn to drive around the sonic territory without any guide post.
