A great 3 pack that includes all of the Phelps favorites.

Maverick Signature AMP Elk Diaphragm: This reed has been specifically designed for the most authentic bugles, and realistic cow calls to meet the demands of World Elk Calling Champion Dirk Durham.

The latex in this reed is stretched tight to an optimum point which allows the call will settle in for the longest possible duration of calling perfection. With this in mind, after 20+ hard bugles, the reed will begin settling in and continue to sound better and better.
