I just purchased a winglock double reed walnut call. Do I need to put some 'voice' (grunt) into this call when I blow? I have read a lot of you like this call and that is what prompted me to buy, but I need a little help in operating it.

I have a Duck Commander 'smoke' and it is ducky without the grunt while blowing.

Any help would be appreciated.
I am also looking for a dozen used dekes (mallards) if anybody has them.
