Phelps Signature AMP Diaphragm Elk Call

The pack includes the Smith, Phelps, and Maverick models, each designed with slight variations in reed tension and cut to produce different tonal qualities. This variety allows you to switch between calls to mimic different elk sounds, such as higher-pitched cow mews or deeper, more aggressive bull bugles, depending on the situation.

Single-reed calls are generally considered the most user-friendly option for beginners because they require less air pressure to operate than multi-reed designs. While there is a learning curve to mastering diaphragm calls, the consistency of this single-reed construction makes it easier to achieve clean, authentic sounds with practice.

Latex is a perishable material that will eventually break down with use and exposure to moisture. With proper care—such as rinsing them with water after use and storing them in a cool, dry place—these calls should last through a full hunting season, though heavy users may notice a change in tone as the latex stretches over time.

These calls are designed to be ready to use straight out of the package. While some experienced callers choose to trim the latex to customize the sound, we recommend using them as-is first to get a feel for the intended tone and performance.

To maximize the lifespan of your calls, store them in a dedicated call case that allows for airflow, which helps prevent mold and keeps the latex from sticking together. Avoid leaving them in direct sunlight or hot vehicles, as heat can degrade the latex and alter the sound.
