Re: Ribbons and Stage Wedges
It depends on how the players hold their instruments. Do the trumpets/trombones hold their horns up or are the playing down? If up, the wedges should actually be aimed fairly close the figure 8 null point. If they don't hold their horns up very well, they may not work. I've only used ribbons a couple of times for a horn section; not live, but in a "live" studio session. There were cranking floor wedges and a live drum kit in the same room (behind the horns) and they posed no problems. That might be quite a bit different than on stage though.
Should work great for saxes with the mic aimed down a bit into the bell.
