Anyone here ever been on or play on a stage like this? Im wondering what it sounds like? Assuming your stage volume is not deafening, you have sound coming from your amp and the monitors like you normally would, but now there are those big columns hanging out in front of you in the air blasting you out over the audience. Do you feel the extra volume more than you hear it? You're behind them, so when you strike a chord or a note, do you feel in your feet more? Does the floor shake?
