Alright, so I'm pretty new at turkey hunting so I have a few questions about calls. I bought the Lil Jack last year, and have been messing around with it on and off. On the end of the striker it is pretty smooth. I was wondering if I take some sandpaper and ruff it up a little will that help me or hurt me? I have seen where folks have talked about tuning their calls but I'm not sure if you can tune a glass call like this? I know there is a ton of knowledge on this site, and I'm extreamly glad to have found it, and be a part of it. If yall have any tips for me with this call it would be greatly appreciated. Thanks for your time and help.
