Custom Color changing acrylic duck call single reed cocobolo tone board

This custom made mallard duck call is made from COLOR changing Acrylic, When its cold its jet black when warm mountain dew color, the color will change as you blow through the call, and has a custom cocobolo wood tone board with a single reed, all my true custom calls are all made right here in the shop one at a time, the tone board inserts are all cut on a custom made jig that was made just for Nor'Easter game calls, each call is hand turned on the lathe one at a time and then hand tuned for the best sound,
