Brian I can assure you that there is a lot more effort put into my calls than you think. The most effort is getting the sound out of something that I make to be the best I can get at that time. Wood boards will not do that no matter how fancy you make them I own the mold that my Cheap Plastic boards come out of and I own the die that the reeds are cut from. I have spent many a hour working with different boards to try to get a good sound some will never get that sound. Until what we call tune by the numbers is done to a set of boards they will not sound good. Have you ever recorded live crows and play back to see what note or frequency that they produce ? I can say this. You make some pretty nice looking calls. Maybe you need to work on getting a good sound out of what you make. Or stick to the decorative class only
