So, I played an opener the other day, for a Cross Canadian Ragweed concert. Big PA, lots of toys. Well, as I'm huddled behind a rack of gear off to the side of the stage right before we go on, I marvel at this toy - a floor rack with a slant top that has a touch-screen "virtual" bank of knobs, sliders, etc. Glancing at some of the virtual controls, I see several modules with a virtual knob labelled "suck knob." Hope they kept those turned down while we were playing!
