I like to use box calls that I make myself from all kinds of wood, cherry seems to have the nicest sound to me and if they were easier to make I would use osage orange, it has a wonderful rasp to it and range, sadly I gave my last one away. This year I am trying a mouth call, so far, not so good, I keep losing my breath and the sounds aren't all that good, trying to master that dod gone 'Kee-Kee Run'!!!!
There's a couple, those are made from curly maple left over gunstock wood.
