Drums
Both on stage and in the studio, Roger's drumming (in the 70s) seemed to
be amplified via condenser mics: Neumann U67s (up to 1975) and U87s (afterwards); on the other hand, these were pretty expensive
so maybe they used them only for video shoots and stuff like that. One was at the snare, the rest in strategical points to
give a more panoramic athmosphere (instead of putting one mic for each tom, for instance). The bass-drum mics were AKG D12
in the early 70's, Beyer M88 in early 80's and D112 in mid 80's.
During the 80s, Roger changed to smaller kits because they were easier to
mike. The mics used were almost the same (now the AKG was D112, which is the most used even nowadays). He started to use electronic
pads too, changing them each tour for newer releases.
Since the band become very famous
(around 'Sheer Heart Attack') the kit would have slightly changes each night, since Roger had many spare parts and the drum
technician could customise the kit differently. Very ocassionally Roger would trash his drums at the end of the concert, so
that's why the spare elements were for too.
