The Sonalksis TBK3 is a compressor capable of such overcompression that it just doesn't jump out on your face, but grabs you by the neck and forces you to stare into your monitor with both amazement and fear. Although the TBK3 can be used on all kinds of material, it's a superior tool for bringing out the evilness in any drums.
The recipe for an electronic drum sound that you can push lunar landers out of orbit with, lies in the combination of using several TBK3s after each other. I found that using two compressors is optimal. One to shape the general feeling of the sound and one to push it over the edge.
