Sounds just like the old Fruity Parametric but it ahs a bigger, more attractive GUI and a built in spectrograph. Very functional and surgical plugin for sure. Personally I seldom use it because I don't like tos ee the music unless my ears are completely stymied.
I recently obtained a Gibson G400 and by doing so, I come to appreciate just how expansive this EQ plugin is. I've used it in other applications but when I incorporate it into an fx bus of an external instrument like an electric guitar, mic, or synth, It really comes into its own. +1 for team Image Line for having some of the greatest native plugins at no additional cost.
