I got just while ago my new bass, and it has done its job really well, but few days ago that horrible buzzing started at A, D and G strings. A is does that on 7th and 8th frets, D on the frets 3-9, and G about from 10 to 16. I´ve turned the truss rod 3 times to left(counterclockwise), and every time I´ve waited about an hour after I did that. And I also have tried to raise those buzzing strings, but they are alreadyreally high, so it really didn´t help much either. So, anyone, help?
