Here's a cool technique I just found while experimenting a bit with my drums:
If your beat is sounding kind of simple, try sending the drum rack (the entire beat, not just one drum sound) to a return, putting reverb on the return (at 100% wet), and sidechain compressing that reverb to the kick. Bring the levels down until it sounds reasonable. I got really good results with that technique. I might post a before-and-after if you guys want to hear what I got with it.
I've also heard a techno song with a reverse reverb on the kick drum, and that gave it sort of a retro sound, so I encourage you to try experimenting with that as well (because I'm too lazy to go through all the resampling for that).
