I usually take an 808 snare + clap sample, and layer that with a small hi-endy type sound from reaktor....EQ each to taste.....I also double compress most of my snares for hugeness, but I am slowly getting bored with this technique......also sometimes I just use white noise and chop it to 1/8 notes, shrink the audio until it is just a quick blast of noise...then run the noise out to a sidechained reverb and EQ the reverb with HPF....
most snares I also EQ out around 4K cause I find it annoying.
Peace
