I use Andy Kaiser custom slate calls, they are amazing. They sound much better than mass produced call. I think I spelled his name right, Ijust looked at the back of one of my slate calls and his signature is hard to read. My wife buys me a call from him every year for our anniversary, so I'm not sure how to get in touch with him. I'll ask her when she gets home and post theweb site, if she will tell me.
