mastering eq

wow, pretty nice sounding eq. doesn't sound anything like the stock version. very sweet midrange, actually sounds sweet all around. Just had a listen to Dave Mcnair's and was quite impressed. Pick up a used one and pop in the $800 board and you've got a nice eq.

Any recommendations? I have the Waves L3 multimaximizer. Should I just use the eq function in that (is it as good as their linear eq?) OR should I use an eq from another manufacturer altogether? I also want something better than the WavesL10 or rennaisance eq.
THANKS for any recommendations.

I recently learned about the 'sweep' technique using a parametric EQ where I set the Q bandwidth as small as it gets (20), the gain up +6dB, and sweep the frequency until I hear 'singers' (frequencies that seem to ring no matter what the instruments are doing) and pull them down -2.4dB.

While it seems more desireable to do this on an individual instrument basis, I've had to do it to a couple 2-track recordings, both which had some similar problems that maybe ya'll can help me with.
