In this free video tutorial, Pro Tools Expert team member Julian Rodgers uses the bx_dynEQ V2 from Plugin Alliance on drums to illustrate how dynamic EQ can be used to selectively deal with problem frequencies on drum overheads.  

Static EQ Vs Dynamic EQ

Using a recording of a poorly tuned drum kit, Julian deals with problem frequencies using a stock Pro Tools EQ and explains how, while this is appropriate for close mics, on the overheads using a static EQ which addresses a problem frequency on the snare will also cut that frequency on the kick. Dynamic EQ can selectively process these sounds, see how in the free video.
