The multiple weights allow the selection of the lightest weight necessary to eliminate the wolf note. A second advantage is that our design eliminates the need for a rubber liner, thumb screw, and a lock nut found on other wolf note suppressors that mount on a string. Installation is simple. The suppressor is pressed onto the string starting at one end of the slot. The suppressor can then be removed and replaced on the string until a position that best suppresses the wolf note. Our wolf note suppressor stays in place, but is easy to readjust if the wolf moves because of humidity changes, etc. In addition to their ease of use, possibly the most important advantage is that the New Harmony wolf note suppressors have minimal or no noticeable effect on the sound of the entire instrument, possibly because there is a direct contact between the string and the brass of our wolf note suppressor.
