The EQ on the Superfly also offers possibilities for controlling room boom. One is to use the software in parametric mode, saving eight presets, with all the filters set for their default frequency, gain and Q save one, which you configure with a .2octave bandwidth, -15dB gain. Starting at 160 Hz save a preset with that filter set at 20 Hz intervals up to 300 Hz. At the gig if there is a boom scroll up through the presets until you find the one that kills the boom. Then adjust the levels of the remaining 'sliders' for your tone. If you find a consistent good setting for the other sliders you can save all of those as well, so that they remain constant while the only change in those eight presets is the boom cut frequency.
That is what I planned on doing. I already know of three rooms we play regularly where I need to control "room boom", and it will be nice to play gigs at the same places and have a preset saved specific to the room. It's nice that on the Superfly you can set it up with both parametric and graphic equalization.
