This is our custom made double sided box call. It is the Greg Abbas signature series. These calls are personally tuned by Greg for ultimate sound quality. No call gets his authentic signature until it meets the high standards of his ears. This call looks and sounds like no other box call you've ever seen or heard. This is by far the best box call on the market. This call has a patented double sound chamber inside the call, creating the most life like sounds you've ever heard! The cedar and walnut that makes this call up, gives it a perfect medium pitch. This call produces both, the sounds of the young Jenny hen, and the raspy sounds of the old boss hen. As with most wooden turkey calls, this call requires oil free chalk. Remember to order your chalk.
