Check the listing for details. Harmony Wolf Suppressor for Violin/Viola Eliminator. Condition: New. Listed at 20.10 USD. Wolf notes are a problem for almost all cellos, many double basses, and a few violins and violas. However, the severity of a wolf note varies with each instrument. The wolf note of some cellos is minor, while others seem almost uncontrollable. Our wolf note suppressors have several advantages. The first is that we provide wolf note suppressors in several weights (3, 5, 7, 9, 11, and 13 gm for cello), (16, 18, 20, 22, and 24 gm for double bass), and (1, and 2 gm) for violin and viola. 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, etc. changes. 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.
