That's what I suspected. Another option I have is just de-EQing the
individual vocal tracks and then bouncing together. That would be
more time consuming, so if it's all the same, I'd like to just de-EQ
the vocals as they are all glommed together on two tracks.

The worst case scenario is to have to redo the vocal editing from
scratch. It's a long nightmare song on an eight-track with little
bits and phrases everywhere because there are so many parts. And I
did a bunch of editing at once, so I'd be starting over from ground
zero and re-editing everything. I barely know what's what and I'd run
the risk of using the wrong stuff. Plus it would take a whole day to
do. So if I can just de-EQ what's already done, that's best.
