I'm not sure why I even had it turned up (it was at about 2 o'clock which I'm assuming isn't the default). I thought maybe I had set it like that because it sounded better during my initial tests but there doesn't seem to be any change in the actual quality of the drum sound. In fact you can't hear it at all in the mix... but I know it's there adding unwanted muck. It's turned down now.
The effect itself though... wow. What an awesome improvement to my drum sound with next to zero fiddling. Sooooo glad they included it. Thanks, Cake.
