I was there when this video was shot and Jason had no idea Ken was doing the video.
You may hear me comment in the background at the end about the call.
Both Jason and I were with Ken the day he picked up the first piece of cane while posting our hunting lease and we have watched his calling making progress.
Because they are cane no two calls, whether they are two or three piece sound exactly the same but I haven't heard a one that won't call a turkey. One thing about these calls is anyone can work one, they are not difficult to master, like a trumpet, and they are much more forgiving.
Just my $.02
