The "Wicked Series" Cherry Crystal Call from Zink Calls is the only custom friction call on the market today that is constructed with impregnated wood. With the impregnation of acrylic into the Brazilian cherry pan it allows the call to be completely weatherproof and the sound quality is unmatched. Combining this to the key features it is a one-of-a-kind, custom friction call. This material is great for not only durability, but sound quality as well. Along with the striker conditioner, the no-slip grip ring and the one-of-a kind built in "Sweet-Spot" for soft calling, the Wicked-Series calls are un-matched.
