Although I had a pedal board for my guitars (overdrive, vol/wah, rotosound, reverb, tuner…) I never really ever considered one for my basses. I’d think tuner and volume pedals would be useful and maybe a chorus to fill out the space when needed, but I get pretty much everything I need out of my bass and amp as is. If I were doing bass centric recordings or in a metal band it would probably be a different story.
Then again, maybe there’s a direct correlation between talent and the number of pedals used, with more pedals indicating more talent - I think it works that way in the guitar world. And that would explain why I have no pedals for my bass.
