OK - First, go get a copy of the Wavez plugins

Take a 909 kick
Apply reverb
Saturate using RBass at around the 50hz point.
Apply a modicum of distortion (quadrafuzz is good)
Roll off the high frequencies.
then...
Layer another sharp kick on top.
Apply distortion to a different frequency range
Boost the frequencies around 80hz
Roll off the high frequencies.
and then...
Layer another kick on top
Boost the frequencies around 120hz

Try experimenting which frequencies to roll off, which areas to boost and which to saturate. Experiment with distortion, reverb, filtering and layer it all together.

Or.....

Get a really hefty kick, have a low sine sub bass and sidechain it heavily to the kick. BoowooahhBoowooahhBoowooah and suchlike.

Makes me happy anyway :lol:
