Have an outdoor gig coming up next weekend. The square footage for the sound to cover is not much different than we're used to indoors. But I haven't played a gig outdoors in a long time. I'm not worred about my DB since it goes through the PA. But for my BG, should I do something different? I have a Genz Benz 6.0 210 plus a GB Neox 112. Stack 'em? Put 'em back on their stands? Put 'em up on milk crates? Or does it not make any difference?
