Waves F6 Floating-Band Dynamic EQ by adrianex
I've had this plug in for little bit with amazing results and its been finding its way more and more into my mixes.
So far has been a miracle worker in overtone and standing waves in guitars and bass.
On drums, it allows me to get aggressive or more creative tones when needed without becoming harsh. And make vocals cut thru the mix without sounding harsh.
Well thought out plug in all the way thru, very musical EQ that allows you to be surgical when you need it to be and easily adaptable to any Mixer work flow.
