I make quite a few gobbler wingbones and gobbler cane yelpers to do gobbler and jake yelps and clucks.
The technique of calling should be pretty similar to what you're doing on any yelper. The call itself is designed to have a deeper tone and to have a slightly slower roll over. You will be pulling a little more air because of the (generally) bigger internals and length, but just remember to draw just as easily as you do on your hen yelpers. I'm sure you will get the hang of it quickly.
