My old huntin' buddy bought a hand made turkey call from an old guy named Turkey George. Turkey George always maintained that the higher pitched the call, the better it worked on those big old toms. His box call is two piece, with the lid separate from the box, and small, like maybe four or five inches long. The box was hard maple, and the lid was of a softer wood. Every time my hunting' pal, and I, went out huntin,' the birds alway went to his call. I tried tuning mine a little, to get a high pitch, but never gained enough to outdo old Turkey George's home made call.
That is a beautiful call by the way.
