Just wanted to show off Karl's calls. He is someone that doesn't really advertise or enter any of the calling contests, but man if you don't own one, then you don't know what you are missing. He builds a true custom call, and even cuts his own glass. He only makes mahogany and walnut pots, and builds a small amount a few times a year. Very highly recommended. I don't know how to post sound files, but you can PM me if you would like me to text or email you a couple. Enjoy.
