It depends on where and when it buzzes. It might be any number of things from too low action, to the need for a truss rod adjustment one way or the other, to the bridge saddles, to something loose on the bass.

Yep, a pro set up is worth the money spent.  I'll add, string type, due to tension of the strings.  Poor fitting nut.  Needs a fret level.  Playing style.  If you can't determine yourself what is causing the buzz, I wouldn't hesitate to take it to a Pro. 
 
I keep the action low on my Rick, but just changing string types can cause issues that need adjustments.  I also play with a pretty light touch.  No buzzing for me right now, cross my fingers.  

I do repair and set up stuff all the time. IF the neck relief is good and you really like to dig in then it might not hurt to raise that string just a bit. I find that playing technique also affects buzz. It's easier to get buzzing when you use a pick to dig in or if you are puling up on the strings with your finger tips.
