Absolutely.....I've had paddle calls made in the south, that took awhile to acclimate to the different weather, here in Pa....
I bought a Snodgrass paddle call years ago, that was a good call, when I bought it.....It's a pure death, non-legal to possess, almost unfair to the gobblers, "KILLER" call now....Butternut under cedar......As it aged, it just got better & better...
Rickey has a sassafrass call from Snoz, that I'd bet the farm is doing the same thing.....
It's amazing how climate affects wood calls....
