this for a more uptempo track
and

for a slower bass

the processing of the bass (eq & dist) is similar i can imagine for different basses (and styles). But the initial bass sound will make a difference in what it really sounds like. These examples are progressive and fullon psytrance. but it also works for minimal style tracks
I kind of know how to produce these basses. But would be interesting to get more people to explain how to produce different basses.
