Hello, I am new to the forum. I am from Louisiana and I have been making calls for about two years now. I finally decided to ask for help. I have been working on bamboo calls lately. They're perfect for where I hunt, plus I really admire Dud Faulk. I love Faulks game calls. Can anyone give me a couple of hints concerning depth of tone channel,as well as degree of downward slope at end of tone board. Thanks very much for your help.
