Probably just raising the string height at the bridge might remedy this. Have you set the intonation on it? (if it's a brand new bass then it's probably already been set)
You'll need a small allen wrench. Turn the two small screws clockwise to raise the strings. Do a little at a time, re-tune the string and see if it still buzzes. Once you get one string to not buzz then move on to the next one. If you notice that the string height is getting too high to get rid of any buzzing then you need to make a truss rod adjustment.
You don't need a luthier to do these adjustments. If there's a music store nearby that sells guitars, there's probably somebody there that could help you. If you post your city, there might even be somebody on this forum is near you.
Here is when it gets tricky....90 % of "buzzing" "Clacking" are truss rod adjustments. SImple as that. One of my issues with Cusotmer service issues on the forum is well meaning people give advice without seeing the instrument and most times it ends up wrong. Just like a doctor cannot properly diagnose your issuewith out seeing you same here.
People usually start with the wrong place..the start messing with the bridge...then the start shimming, over tightening the truss rod...and really just take it to your favorite dealer and watch the guy tweak the rod and you should be good to go....
So much of our customer service/warranty work is by owners attempts at set up.
Freddels, thanks again for staying with me on this, I appreciate your help.
And Sterling, I also appreciate your perspective on this. You've probably seen a lot of "home diagnoses" that turn out wrong.
Taking both of your advice into account, I will try to make more truss rod adjustment, and if it still doesn't work, then maybe I'll try very minor adjustment to the bridge. If still no help, I shall find a BG expert in my area (Walnut Creek or Concord, in the San Francisco Bay Area). In fact, I may do that before trying bridge adjustment myself, if the truss rod solution doesn't work.
