I've tried everything, my strings are literally 5 mm from the fretboard and are still buzzing no matter how much I keep turning the truss rod or messing with the bridge. I've watched like 6 videos so far on how to set it up and at this point I'm convinced that the buzzing isn't because of me but because the bass might have been horribly engineered. I'm completely hopeless at this point, please tell me if I'm missing maybe missing anything here, I understand that setting up an instrument takes patience and time but this just has to be the most frustrating thing that I've ever been through. And by the way, I don't think luthiers even exist in my city so I can't really even have it professionally set up. The bass is a Yamaha TRBX174 for anyone wondering.
