The bridge plate on my F-50 had worn to the point that the windings were coming through far enough that some of them were on, or very close to, the saddle. Coincidentally, the sound of the guitar had deteriorated, at least to my mind. The luthier who worked on it just put a new plate over the old one rather than mess with trying to remove it. He used ziricote, and it improved the sound, or at least restored it to what it had been before the deterioration, or so it seemed. I don't know if that was due to the new improved plate or to the fact that the strings were seated properly. I suppose the latter would be due to the plate as well.
Just my take.
