I'm interested in learning more about techniques for hat mic placement from underneath, the idea being to save on stage footprint by using a clamp on a snare mic stand or the hat stand itself. With a closed or partially open hat, the sound wouldn't be that different than with placing the mic above, but what about when the hat is completely open and the top cymbal played? If this is a workable strategy, what clamps have you found to be useful -- I know Atlas sells a clamp-on swivel adaptor that's reasonable, are there others?
