Eq your whole mix: Cut entirely at 16khz but make the bandwidth drop sharp (it keeps the buzzing high freqencies while removing the harsh, uncontrollable ones). Cut at 70-90hz as needed (depends on how much bass you want in your mix), and cut a little at 250hz and 670hz (to deal with muddiness and clipping issues, respectively).
Eq your synths: Pretty much same as the eq for the whole mix. I cut all the bass, a little at 250, and the same settings as above for 16khz.
Eq your percussion: Not all of your percussion should be eq'd, but high hats can get a little too harsh and brushy. I cut all frequencies below 700hz for this, and once again the same settings as above for 16khz.

what if it sounds good in the mix but shit during its solo, eh eh eh
The simple answer to this question is that if it sounds enormous, fat, obese, whatever you want to call it, when it's soloed, it is going to crowd the others in the mix.
Solution: Make EQd version for the one destined for the mix and one un-EQd version (fat) for when it's in the breakdown.
You see, sometimes it is hard work that get's the good results!
