• Made in the USA
• Complete Elk Vocalization System: The Phelps AMP diaphragm elk call produces the full range of elk sounds, from soft cow chirps and calf mews to aggressive bull bugles and chuckles, all from one hands-free mouth call so you stay ready with your bow or rifle.
• Built On The Proven AMP Frame: Every AMP diaphragm rides on the signature aluminum frame with precision-stretched latex for a comfortable seal, consistent tone, and long calling life. The reeds break in and sound better the more you run them.
• A Reed For Every Caller: Pick the latex and stretch that fits your style, from easy beginner reeds to competition cuts run by World Elk Calling Champions. Lighter latex needs less air for cow and calf sounds; tighter latex drives loud, high location bugles.
• Hands-Free When It Counts: Keep the diaphragm in your mouth while you draw and hold, so you can stop a bull at the moment of truth without reaching for another call. Ideal for archery and rifle elk hunting through the September rut.
• Designed, Tuned & Tested In The USA: Phelps Game Calls builds and tunes each reed in Washington State, trusted by champion callers and backcountry hunters. Store your calls in a cool, dry case to protect the latex and extend their life.
