Always a great question.There are so many great ones out there and today there are so many custom call makers to choose from, When I first started my favorite was a Ben Lee champion gobble box call. However, when he passed away, I retired that call.
Today, my go to box call is a Mike Lapp short box in Black Limba and Yellow Heart. What a great call
I have a long box from Mike that is unreal but I have a bunch of signatures on it from call makers that were in Nashville, I don't use it in the woods. I do really enjoy long box calls and I have several that I hunt with, Ed Terefencko, Tim Bullock, Mark McLaughlin to name a few. All great calls that have turkey under my belt using them.
Safe hunting and hope everyone enjoys their favorite box call!
