Beyerdynamic M 88 TG mic

Hypercardioid dynamic microphone. The TourGroup (TG) version has a reinforced basket to better withstand the rough handling of live touring.

Mentioned in Kerry's first "Tech Tuesday" blog post on 2009/09/15 as part of a run-down of mics used to capture Mike's drum sound:

On the outside of the kick and about 4" from drum head we are using 2 microphones a Beyer M88 TG (this is nice for that super tight low end punch) and an AKG D30 (This is the microphone that was used to get that huge kick drum sound used on many Led Zeppelin recordings. We call it of course the "Zep Mic".)
