I record vocal tracks direct in with no room volume on, and my early projects saw the vocals really boxy so I used the parametrics on the mixer and now they are worse than even. I need to set them back to flat and record the vocals on this song again. I mean it's only 5 minutes out of my life, but geeze....

I will try those plugins. What I am missing is feeding back out of the DAW into a real mixer. A physical, tangible mixer that I can touch and work sliders rather than moving a mouse. Everything on this track is fine except the megaphone vocals. They really suck.
