Update, after many duck inserts I have produced one that sounds dang good. Hopefully it’s not a happy accident. Now, to continue to refine, and get repeatability.
Years ago I stood in Alvin Taylor’s call shop in Arkansas, bought a few calls from him and talked for a few hours about many things, but little about call building...sure wish I could spend another afternoon with him in his shop.
Funny thing is, he was learning to work with Corian, and commented how he would do the next corian call different. Even an experienced call maker like him was still learning.
I bought that call and it is the best sounding call I own.
