I've had some very good luck with Haydel calls. They are all closed reed, but they make Jackrabbit, cottontail, fawn, woodpecker, howler and several others. Rush Sporting Goods in Russellville carries a pretty good stock. Cross Creek in Fort Smith also carries a few. I think you can also order off of their website. The Government Hunter Model had two different sounds. But if you give on a try, I think that you will like it as well as you like their crow call.
I have several different brands of call, JS, Burnham Brothers, Weems, Lohman, Primos and others, but Haydel calls are as good as any on the market.
