It seems to me everyone is forgeting the actually Frequency of the bass. No matter how good the quality of the bass line, it will SUCK and sound "computerish" if the right frequencies are not emphisized. If you don't know how to eq...use one of the many VST effects that are on the web. One of my personal favorite is MAXXbass, and it has a cool woodgrain interface. I've made the cheesiest sounding basses hot by using eq to my advantage.
