Not only has Tim Grounds put more duck in the new “D” Overhauler, but he has made it easy for you to get it out. The new Quarter Barrel Mouth Piece design reduces both, the amount of air needed to run the call, and the distance from your mouth to the reed by almost 25 %. This creates an easy blowing call with the natural rattle of a nasty ol’ hen. Its newly designed insert boasts a tone board that drops like a mallard comin’ in to floating acorns, giving the reed freedom to move and flex further, creating unmatched tonal control. It also has a tapered ream sound chamber for unbelievable volume on those windy days. So it doesn’t matter if you’re soft talkin’ while standing in timber, or high-ballin’ while sitting in a pit, this call will getcha some .. I promise. Made in the USA.
