Although the "grunge rock" genre might seem quite homogeneous if you are not used to it, all of those bands have quite different styles (and especially the bass players). I'm not sure there is one "grunge" sound that would work with all of these, but as others have already suggested, plenty of mids in your EQ will definitely help with making the bass heard - too bassy and it will turn to mud.
Out of all that lot I would say that some of my favourite bass lines come from the Stone Temple Pilots. No idea what bass he uses though! Plush is an awesome track
