The first thing I'd want to be certain of is this: Does the zing Come from the string, Or any thing, In the key that’s pressed When the owner is blessed To hear that awful, cursed ring? In less poetic(?) terms: I would not automatically assume that G#6 is the source of the noise even though it is the key that generates it. Huh? I had a Wurly console with a zing thing that drove me buggy. I think it was on A4. Turned out to be the lid lock mechanism. No other note would make it buzz. Had a Baldwin grand where D#6 (if memory serves) made a distinctly annoying little sound. Turned out to be the small lid prop bzzzzing against the large lid prop. Missing piece of felt. Had a 1963 Lowrey Console (Oog) with a little zing ring at D5. Turned out to be one string not damping well on G3--it was just really responsive to that particular overtone. Had a zing that was very loud and pronounced on some note or other in an old upright. Turned out to be coming from a small object d'art (figurine) sitting on a glass end table five feet away. Hide and go seek. Bon Chance! Alan R.

Maybe?
