I think that's not entirely correct Aidan, as it's pretty clear that there is a blue ring around the wire mesh wind guard. The blue ring is unique to the Beta series mics afaik. If you look at any other Elevation, Vertigo or 360 tour pic, it's the same, a Beta 58 wireless. The models might be slightly different, but always Beta series.
From my understanding and from reports in various trade journals re: U2 recording sessions and touring equipment, Bono's been recording into wired Beta 58s since at least ATYCLB sessions, and touring with a wireless Beta 58 since at least the Elevation tour. I can't be bothered to check Pop but I'm fairly confident that for about 10 years now it's been all Beta 58s.
