A game call apparatus is provided which has a mouthpiece including an air inlet, a reed positioned in the mouthpiece and vibrating when air is blown into the mouthpiece, and inner and outer tubular sound chambers mounted on an air outlet end of the mouthpiece. The reed is mounted on an air inlet end of the inner tubular sound chamber, and an air outlet end of the inner tubular sound chamber extends into the outer tubular sound chamber. The outer tubular chamber has an air exit end which tapers radially inwardly toward an air exit. The air exit end includes the air exit which is smaller than an air outlet of the inner tubular chamber. The taper and small exit opening of the outer tubular chamber provides a back pressure to air blown into the mouthpiece which produces a realistic game call sound as the reed vibrates.
