I'm with Alan Hyatt on this one. When it comes to vocals, I never eq while tracking (i.e., going to tape) for several reasons:
1. Most board eqs aren't surgical enough to do any fine adjustments and they affect too broad a range of notes. Plus, you're adding phase distortions and messing with the time constants of the original signal, which CAN'T be restored later.
2. The eq settings become just one more thing to remember if you have to punch in a line a few days or weeks later.
3. I come from the old school (like Alan) where you learned that mic placement and mic choice was your eq. Boards (when I started) had maybe two eq knobs; high, and low. We didn't use them all that much.
If you have the luxury of several mics to choose from, the best results will still be had by using the correct mic in the correct position, then make adjustments during the mixdown phase, if you have to adjust it.
Microphones are like flavors; you try to choose the right flavor that compliments the artist as perfectly as possible. Sometimes, it's a Neumann 67 with a .6 micron Stephen Paul diaphragm (a very expensive delicate flavor), and sometimes, it's a Radio Shack megaphone (a gritty taste).
The trend seems to be to just put up the mic and if it doesn't sound right, reach for knobs and start turning. You might get better results by having the artist move around and try different angles and distances, or try a few other mics, before you start "fixing things" with eq.
