I know what you're getting at, however I would venture there is maybe a bit more to it all than that. We both know that at times a hot two year old gobbler would respond to the shrills of a beagle caught in a fence or a rusty gate swinging in the breeze. Some calls definitely sound better than others. Do you always need a refined call? No, but it never actually hurts your success. There's also pride in ownership. For some guys they could care less and a blister packaged Walmart call is good enough. Other folks appreciate craftsmanship. The same thing applies to guns, knives, clothing, ect. For sure if a feller wanted, a few $6 dollar mouth diaphragms are all the calls actually needed. I like and use mouth calls but I really enjoy working a nice friction call. So I have some well crafted friction calls that make me happy. If a box store call works for the guy on the other ridge, more power to him. As long as we're both happy, what's the harm?
