My daughter's violin had the wolf on B note of G string and I went to the best Luther in my city. He told me most of the Italian violin got wolf tones and It's hard to make it disappears.
He told me it needed to open the violin and take very long time to fix it and he is not 100% sure if he can make it disappear.
I read an article about René A. Morel fixed Sarah Chang's Del Gesu wolf tone. but sadly he passed away on 2011.
I wondering if it worthy to give a try? any thoughts? thanks a lot!
