this article. Good explanation of the importance of reverb, EQ, and compression, the resources linked from it are OK too. It mentions "subtractive EQ" which I didn't know much about when writing this resource.
Basically, if you don't wanna read the article, subtractive EQ is a technique where you only reduce frequencies rather than increase them. It gives somewhat of a better sound than boosting them since the frequencies you want are probably already there. You can't always avoid boosting frequencies so don't be too **** about this but it's just better to err on the side of subtractive.
