The Rolling Thunder Game Calls Josh Grossenbacher Signature is a threereed diaphragm call built with a combo cut and a relief cut in the middle reed, creating a versatile sound profile capable of producing the full range of hen vocalizations. Constructed from heavy latex reeds in a gray color pattern, the call is tuned for clarity, rasp, and control, supporting everything from soft tree yelps during early morning setups to loud, aggressive yelps and sharp cuts used to trigger gobbles at distance. The combination of reed thickness and precise cut geometry provides a natural break in tone, giving the call a realistic cadence suited for both subtle and highintensity calling sequences. Designed by world champion caller Josh Grossenbacher, the call reflects the craftsmanship and tuning expertise he is known for. Its responsive airflow and balanced reed tension allow for smooth transitions between gentle hen talk and demanding, gobbleinvoking sequences. With its blend of power, finesse, and tonal range, the Josh Grossenbacher Signature diaphragm call offers a dependable option for hunters seeking a versatile threereed design capable of handling varied situations throughout the turkey season.
