Calling elk is filled with nuance. The All-American diaphragms were designed with those nuances in mind for the ultimate user experience. Ever wondered how competitive callers deliver those realistic elk sounds on stage and in the field?  Phelps teamed up with three RMEF World Champion competitive elk callers to bring you a series of diaphragms to perform at every level in the most important contest of all, between you and a wild bull elk.
 

Pack includes three world champ diaphragm elk calls: 
 

• World Champ Jermaine Hodge: 

“My Hodge masterpiece call is designed to make elk vocalizations as simple as possible. This call offers the versatility of the Pink Phelps Signature and the Large Bull Sounds of the White AMP giving you the ability to make calf to large bull vocalizations. This could be the only diaphragm you may ever need in the woods during elk season. Field tested and elk approved.”
 

• World Champ Tony Gilbertson: 

“My Gilbertson diaphragm is specifically designed for callers who want to reach out to bulls with loud location bugles, or punch them in the face with a fierce challenge bugle! From bull sounds to cow and calf communications, this diaphragm is arguably one of the most versatile on the market. A break in period is required on this diaphragm, but the tight stretch on the latex assures longevity and stands up to abuse to help seal the deal in those crucial moments in the elk woods.”
 

• World Champ Erik Berglund: 

“My Berglund signature diaphragm was specifically designed for every archery elk hunter,  and still meets my every demand. The latex used is a little thicker than the Maverick,  and stretched a little tighter to allow for a caller to make those authentic bugles, mature cow calls and high pitched calf calls. It’s truly a world class call.”
