id also recommend slapping a waves renaissance bass on there. but go easy on it. and play with it for ages too.

itll take good care of the bottom end of the sound, and you can concentrate on making the mids sound fat.

also, many basses that sound as if they start on the offbeat actually start on the second 16... for example alot of uberdruck b-lines. you can get a really nice groove and achieve some nice kick/bass pressure.
