Yesss, the Gyratec XIV Stereo Parallel-passive Equalizer comes to mind.. but with it's linked channels it's rather for mastering or stereo-only signals than for a handy kick/snare combo.. I even wouldn't mind an eq solely for THAT purpose. Think about it, kick and snare have similar needs for sweetening, but need different frequencies. It would be a good selling point to stand apart from the multitude of mee-too EQs. Because, that's the reason stuff sells, it's good at something all the other boxes won't do as gracefully.
I just thought of a name: the backbeat box. Does anybody else think this is a good idea? After all, in MY workflow it's not about unnerving the band by fiddling with the knobs for half an hour getting a sound but get results fast so the band (everyone together in the room, gentlemen!) can stay in the flow.
And I don't insist on a passive EQ (which sometimes is just too sweet on drums), it could be anything in topology. But that would be Alberts job
