I about to start recording a band in which the drummer has 2 huge floor toms, 16X18 and 18x18. They sound really great in the room, but when they record they sound like someone hitting a bucket with a notebook on top, no resonance and no fundamental. I am using Audix D2 mics on the top on their D-vice clamps about 2 inches up and pointed at the impact point. This same placement with D2s sounds excellent on the rack toms. Does anyone have any ideas?????
