Rocky Mountain Hunting Calls & Supplies Bully Bull Elk Grunt Tube

Yes, the Bully Bull Extreme is designed specifically to work in tandem with a diaphragm call. It acts as an extension of your vocal tract, providing the necessary back pressure to amplify and refine the sounds you create with the diaphragm.

The Tube Tamer is an internal component that helps smooth out the airflow and reduce harsh vibrations. It essentially cleans up the sound, making it easier for you to hit precise octave changes and produce more realistic, natural-sounding bugles.

At 21.375 inches, it is a full-sized tube, which is standard for achieving the deep, resonant tones required for elk calling. It comes with a lanyard, so you can easily carry it hands-free around your neck while moving through the woods.

Yes, the camo cover is designed to be durable for field use but can be removed if you need to clean the tube or store it in a more compact space. Keeping the tube clean ensures the internal acoustics remain consistent over time.

The 1.5-inch opening is sized to provide a comfortable seal for your mouth while maintaining the right amount of back pressure. It is wide enough to allow for a full volume of air, which is critical for projecting bugles over long distances.
