I felt the same way after I spent a thousand dollars on the best calls and coudn't make a goose sound after months of trying. I just had to keep using my flute, but it killed geese. Then one afternoon my buddy met me at a city park with ducks and geese. He worked with me for about an hour, but I was able to finallyable to make a couple of goose sounds. After that it was all down hill. I was practicing in my car at home at work. My boss even told me he was gonna fire me if he caught me blowing it around customers. You just have to get someone to help, or you gotta stick with it and keep trying! It's not the call that sounds like a goose it's the caller. Good Luck!!!
