Yeah they could do with being a little longer, but hey at least they're going into that much detail, which is rare for a big band. A lot of the new(ish) bands have been doing this for the past few years, being very open and honest about what's being used, but I've always found the older, bigger names try to keep their cards close to their chest. Big respect to Machine Head for doing this and realising there are people out there who actually give a shit.
Haha, I find this amusing after watching the drum video as I'm halfway through an album on which I also used our Dunnett T1 and top/side/bottom mic'd it also.
