A single reed turkey gobble call includes a barrel through which a user blows air. A reed assembly is positioned in the barrel. The reed assembly includes a tone board and a reed positioned against the tone board. A wedge engages the reed, and the reed is partially clamped between the wedge and the tone board such that a distal end of the reed is free to vibrate against the tone board. A vertex is defined on the tone board at the location where the reed separates from the tone board. The wedge is axially offset from the vertex in the axial direction away from the distal reed end by a wedge offset distance to produce a gobble sound.
