Hey guys, My father-in-law has recently jumped into making duck calls, not so much to sell them, but for the enjoyment and challenge. So far he's done very well with them and is turning out some neat looking calls - as for sound, he's hitting a good one at about 1 in 5 right now. Does anyone else on here make them? Do you have any good resources to pull from with tips, suggestions, or ideas? As of right now, he's taking the good ones he's made, and patterning them to try and get more consistent. It's amazing how such minor differences between two calls made with the same pattern will have such a varying tone!
