No doubt that experience is the way to go, but I am "burning" to tape Springsteen and as he is turning 60 I am afraid that this is my last chance, at least with The E Street Band.
Advice from someone who has taped MANY Bruce shows, in arenas and stadiums:
What everyone said - get the mics off your body and into a hat. It will help a lot, especially if you're in the GA section on the field. You can also set the hat a little further back on your head if the hanging stacks are above you.
Every stadium is different - sometimes they put repeater speakers half way back, sometimes not. Record in 24 bit, peak at -6 to -9, and be aware the show can get louder as it goes, especially when the crowd goes nuts.
Location, Location, Location. I have lousy seats for one show, buried deep underneath an overhang - the sound from there will probably not be worth taping (not that I won't try).
Good luck, and welcome to the taping community!
