Agree with all of the above. Also, my guitar sounds carp through my bass effects, probably the built in EQ emphasis (he says as if he knows anything about the technical bits).
Individual pedal wise I know some guitar pedals are used to good effect by bassists but it's horses for courses. It depends what other gear you use and how you play. For example, some bass pedals that sounded awesome with my passive p bass were terrible with my active jazz bass, amps can have a big influence on sound too. Unfortunately it's just one more thing to research and experiment with, the endless trial and error!
