Those drum-mics were developed after taking a speaker from Yamaha NS-10 Monitor and reverse-wiring it to make it into a giant microphone diaphragm became a trend in studios. Larger diaphragms are better at reproducing low frequencies, and these are particularly good with sub-bass frequencies, the stuff you feel, not so much hear. The argument could be easily made that this change might “muddy” things up, especially in a big stadium.
I have never heard AUDs from Hampton before this run, and I’ve heard a few different sources, and I think they ultimately sound more aggressive and exiting than the soundboards. This is a testament to the acoustics of the place.
I was prepared for this new guy to be noticeably not-as-good as Paul, and I have to say that I was totally wrong. I think he did a great job, and I think Page and particularly Mike sound really good in all the recordings I’ve heard, including SBDs. If anything the bass guitar on the SBD’s sound like the mid-range is more defined than normal, which I think makes sense. Bass waves are very long and tend to bounce around big rooms, so I can imagine that if you were mixing something for a stadium, you would want to hype the mid range so it didn’t get lost. I think Mike’s playing gets lost a lot, and in these recordings he is very present.
