Phelps AMP Pitch Black Series Diaphragm Call, 3-Pk

Pitch Black 1: Has a looser stretch for easy cow calls and all of the bull vocalizations. Very easy to use and quiet when needed.
Pitch Black 2: Has a medium stretch similar to the popular Maverick and Phelps Signature diaphragms. This is a do it all call.
Pitch Black 3: Stretched tight for ear piercing location bugles as well as higher pitched cow/calf sounds. The best thing about this call is the life you get out of it.
