errrrm right...
Take 1 thuddy snare (that almost sounds like a tom) and beef it up at it's sweet spot (normally around 200hz)
Put a fizzy snare on top of this to add errrr fizz....roll the bottom of this so it doesn't clash with the thuddy snare.
Add either a snappy snare or clap to give it snap....rolll the bottoms off this too if the freqs are clashing at all.
The thuddy snare is going to give the overall snare power whilst the clap and fizz are there to add character.
...all you need now is to piss about with each channel's levels until they sit nice.
...oh and depending on what effect you're going for you might wanna make all the snare lengths the same as well.
job done.
exactly this
