Reduce sharp snare overtones
Snare drums are probably the most finicky. Even with a fresh set of heads and a mountain of tuning experience, sometimes they won't cooperate fully.
Just one piece of Drum Honey on the batter head can bring down the overtones and ringing to a comfortable level.
Or, if you're just feeling a different vibe, add several pieces and turn your snare into an entirely new drum. Hello 1970s boxy studio sound.
