Reply to Production Books that get into EQing and such

Hi all, I'm looking for a decent book that covers something I don't know a whole lot about: EQing, and frequencies in general. Basically, I need a book that covers everything that isn't about synths and creating rhythm patterns and song structure and all that kind of thing.

What I'm trying to say is that I can already make a sound that has what I want, I just need to learn how to make it sound good, from a technical perspective.

Any thoughts?
