The short mouthpiece of the goose call is provided with a bushing which telescopically mounts in the mouthpiece bore. A relatively long belled tube mounts to the bushing in order to produce a sound-projecting megaphone effect for the instrument. Further, the reed is truncated in comparison with the reed of a conventional reed assembly, to an extent such that the free end of the reed is substantially coincident with the end edge of the sound trough. Percussive sound, as a result of blowing on the mouthpiece to cause the reed to vibrate, consequently is produced primarily by repetitive flapping of the reed aganist the side margins of the mouth of the sound trough, a crisper herr-onk break is more easily achieved, and the tendency of moisture or ice to cause the free end portion of the reed to non-vibratingly adhere to the mouth surface of the sound trough is reduced.
