This is a closed reed distress made from cocobolo.The call is made from cocobolo and it might have some sapwood, which I really like, I think it adds to the call..I can voice it in cotton tail. Jack rabbit both in double reeds or the new coaxer that also does a fantastic bird distress. Please let me know how you would like it voiced when ordering.. This is not the exact call you will receive just a represenative of it.
