I got a new bass about 12 days ago. At the time we’d had the driest and hottest month of May for decades. The grass was dying and the air was very dry. My bass had a nice low action. Then the rain came and the last few days it’s been foggy. So a lot of moisture has been hanging around fir at least a week. I guess the neck has shifted because I suddenly started to notice bad fret buzz, especially on the D string. Today it’s been across A to G From around the 4th fret down. I loosened the truss rod about 3/4 of a turn, a little at a time. The buzz has improved and is now only below 12th fret and not as bad. But the action has gone up as a result. Is there any benefit in continuing to loosen the neck when the buzz now begins where the neck joins the body? Should I take this to a luthier rather than risk messing things up? I’ve adjusted minor neck issues in the past but I’m not very experienced in this. Does the neck need a shim? Is it possible that this bass has a very unstable neck and will need a lot of care and attention as the seasons change?
