My first violin has a HUGE wolf on the G string on the high C#. :( i hate wolves.
Anyway, the new fiddle I'm playing on doesn't seem to have any... yet I only recently learned what these were from reading the Discussion on this site. I haven't heard one though, and am not sure I'd know what one sounded like if I did. Is it possible to put a good (obvious) example up online and link to it? I have a couple mild wolf tones in the B-flat to C range on the G-string on my older violin.
On my new violin, I had some wolf tones on the B-flat on the D and A string and E-flat on the A string. These were essentially eliminated after acoustic optimization by (V-com member) Stephen Perry of Gianna Violins. Thanks Stephen! When I used Tonicas, my violin had a wolf tone at the C# 1 & 1/2 octaves up the G string. I do not have this problem with Evah Pirazzis. High C on the G string. If you baby it, you can still make a good tone there, but it's about like walking on a blister. I used to think that the existence of a wolf tone in a violin (or any stringed instrument, for that matter) was not depending of the kind/brand of string or of the concrete string (I mean, if you have a wolf tone in your high C in your G string, the wolf tone should appear in that tone in every string, even if it is harder to produce). It has something to do with the resonance of the back of the instrument (I think).

Karen, follow this link: the example is pretty clear :) http://en.wikipedia.org/wiki/Wolf_tone

I can get a strange high piercing tone on my open string when I press in 1st position G on my D string, and B on my A string. The velocity of my bow can be fast or slow. Once it catches this pitch it can hang on for the entire length of the bow stroke. It sounds like the e5 overtone, my open e pitch cuts out. I had a student with the same problem. It makes it hard to do Bach's works for unaccompanied violin.
This has baffled two violin makers, a physicist and two of my former teachers. I've changed strings a variety of times, different ones, synthetics and aluminum wound on gut.
Any ideas? My middle 'C' on the G-string "Honks!" like a goose after a while has passed. Not long after that the G-string needs replaced for it just dies shortly after the first honks. (Goose Tones?) I used to have to deal with a wolf on my G string. In those days I adjusted some things myself until it stopped.
Recently I took my violin in to a luthier for some work. It has been about 35 years since my poor old friend has been in to see a professional. Now everything is perfect.

Most of the C/C# note seems to be a little "over resonance" or simply a little louder than the rest.

But this only noticeable under ear, I think listeners don't notice it or simply non existance in listener's perspective. By listening the echo of my violin when playing in echoey room/hall, every note seems to have equal volume, so I'm happy.
