THIS is fuckin cooool!
As for the mud? I think it adds character, gives all the other sounds a foundation to stand on much like bass does, on the issue of taking it out, it's hard to deal with sounds at that octave like this. They lose a lot of their bite, or rather, it's like they get a massive underbite that drags on the fuckin floor.
if I ever find a way around it besides EQing and VST perversion i hope I remember to let you know if you don't figure out your own method
