NHM wolf note suppressors have several advantages.

• They are available in several different weights which allow the selection of the lightest weight necessary to eliminate the wolf note.
• Their 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.
