Heifetz Mute for Violin or Viola

The unique design of the Heifetz mute allows the player to adjust the muting effect by sliding the metal tension clip down or up, muting more or less as a result. The metal tension clip is the part that is stamped HEIFETZ. Made of the highest quality materials, many professionals swear by this unique mute. The original Heifetz mute was very similar, but with a slightly different design.
