Once the drummer has set up and the engineer has placed all the mics, take a single sheet of paper and place it on top of the snare drum.
It can be any type of paper. I usually grab a sheet from the computer printer. I'm sure you could even get away with tearing out a page from a magazine.
You will probably have to apply gaffing tape for the paper to adhere to the drum.
Return to the control room and have the drummer whack the drum with a stick.
Listen for the differences between the paper on and off the snare drum.
The sound derived is pretty much what you'd expect. It will give more of a smack to the snare sound and really embellishes the the snare strainer sound.
In a recording situation, these simple little tricks make the difference between a run-of-the-mill sort of sound and one truly unique to the recording.
This technique works very well at accentuating the nuances of a snare roll-very similar to how you'd expect a marching snare to sound.
