We made an EQ rack that work's like the one Richie Hawtin put in the forthcoming Model 1 mixer. It's a fun little sound isolator, which we've tuned to work well on a master channel or drum bus. We've also packed a master channel we find ourselves using all the time lately. Enjoy it!
A quick note - there's a Utility in there with our "stereo to mono" setting. You'll want to adjust this to suit your needs. Additionally, the HPF (bass kill knob) and LPF (treble kill knob) actually turn off the filter at the respective top and bottom of the frequency sweeps. This is happening so that you can also use the knobs as a kill switch - bring the low "all the way up" and high "all the way down," and you'll find the filters deactivated.
