Re: Dead Note\Wolf tone moving up in pitch

"This is really fascinating indeed, If tailpiece mass or bridge mess
can have such effect how do builders actually solve dead notes
appriory?"

Trial and error, my friend.

The basic cause of any dead note or wolf note is a strong resonance
someplace that can interact with the string or another part of the
guitar. It could be the bridge, the tailpiece, the top, the back
strings; there are lots of things that can do it. It could even be the
reationship between a couple of things that, by themselves, wouldn't
be problems.

Swapping out the tailpiece altered the pitch. See if adding mass to
the tailpiece makes a difference. Try putting something, like a piece
of cloth, between the back strings between the tailpiece and the
bridge to damp those short lengths of string. The mass added to the
bridge may well have helped simply because it kept the bridge from
moving enough to get the tailpiece going. Or maybe not. You've got to
think about what might be taking that string energy out and losing it,
and there is a heck of a long list of possibilities. Experience helps
in figuring out which ones are the most likely, but ultimately the
only way to tell for sure is to try something.
