1. You would have to ask a crew member..I have no idea..Sounds more like a tech guy to me then Edge ….

    the original mix a few years back wasn't an IEM….those usually sound flat to me..all the bands members instruments sound crisp..but again Im not an audio guy...
  2. As far as I can remember, you could hear this remark in the stadium itself, so no IEM source.
  3. OK...thanks! It once again states how impressive this recording is
    - not sure if I like the remaster, but I guess not everyone likes mine as well
    (Hope to dig out the original recording one of these days - u2torrents says I must have it!)
