Hey guys, I need to pick the brain of you duck call masters. I got a guy who wants a reelfoot looking call but with a Arkansas style insert. My normal barrels are 2 3/4" and the one I've made for this call is 4" long. I tried it with my normal insert length and it just wasn't happening. It sounded flat. Next, I added about 3/4" to the overall length of the insert, not the toneboard, just between the cork notch and where the insert stops at the barrel and still no joy. Any tips or ideas on what I can try? Any help would be appreciated.
