What you’re hearing is most frequently (if not always) associated with strings going bad. When the core breaks down this weird phenomenon happens. You also tend to hear the pitch fluctuate as you add and remove heavier bow pressure. When the luthier did the restoration, dis they put on new strings or put older ones on? How long ago was the restoration performed, and was it allowed to sit a long time after?
