How do I get that full bass sound?

I've also realised that often times the only thing that should be occupying those REALLY low frequency parts of the mix is the tail end of the kick to really have it thump through the bottom end.

Also if you make sure that the decay on the kick is such that it leaves at least 1/4 of a step of silence the track will sound so much punchier rather than just a wall of bass. Bass dynamics matter big time IMO.

My advice is keep it simple. I used to spend hours trying to come up with some really fat bass, but then i found that it was usually to over powering and wouldnt balance out in the mix. Make sure the bass compliments your kick drum.
