Hold the call by the bottom, not the sides, as this deadens the tone. Also, never touch the sound-producing surfaces with your fingers. Skin oils can damage the call. Whether you hold the lid handle toward you or aimed up doesn't matter. In fact, try it several ways to see which works best for you. To tune the call, adjust the screw holding the lid, one turn at a time. You want it to make a clear, raspy yelp. Never lift the lid from the box while calling, but try applying different levels of pressure to produce varied tones.
