Ed,

If you are talking MIX, then you need to work on the mix, not the master.

Clarity can often be had by even broad-stroke EQ rules of thumb.

First rule of thumb that I use: With vocal tracks, and almost any instrument besides kick drum and bass guitar; high pass filter those tracks starting at 150 Hz or so and go up from there until you start to hear the instrument or vocal get too 'thin', then back off the frequency a little from that point.

Just start with that single rule of thumb.

You'll be amazed what can happen to a mix once you then put the whole thing through some kind of mastering plugin.

If you haven't already done this with your individual tracks, I lay a challenge out before you to do this.

I think you'll like the results.
