The present invention discloses an animal call device, which operates by a user blowing into the mouthpiece of the call body, such that the flow of air causes an internal reed to vibrate, with the air flowing out through a resonator, creating a sound that emulates the calls and grunts of a deer; with the present invention incorporating a moveable slide that presses against and dynamically alters the vibratory properties of the reed, thereby changing the sounds that are created by the animal call device.
