I use an EQ hi and lo cut filters on an insert after the inserted reverb on a send. Believe it or not, I cut up pretty high, up to 250hz on most reverbs and also cut out just about everything above 12khz as well. When it comes to vocals, I'll also add the same EQ that i might have boosted the vocal with and use that same EQ on the send after the initial EQ that's removing frequencies generally above and below a certain point and I'll also pull down a little bit until the vocal pops in areas I've boosted. I'm knowing for setting the voice pretty into the track because I like guitars to be at the same volume, but somehow people say my vocals are still heard fine. I think it's because of this. As an example, if I've boosted 700hz with a UAD 1073 on the vocal buss. On the vocal send, I'll load another 1073 and cut there. Point is, if I've boosted somewhere in the vocal, I've done it for a reason and feeding that frequency boosted to the reverb will make the reverb respond to that particular frequency's boosted gain. I don't need my reverb working double duty on that frequency. I'll sweep somewhere in the mids until I find a frequency I like for that and voice to get boosted while making sure I've cut where I've booste on the vocal. Does this make sense? You keep your reverb dense and smooth without the muddiness this way...especially if you're mixing in the box like I do, every advantage you have over analog should be used.
