Some of y'all have seen or watched a portion of Shane Simpsons mouth call mechanics video. I have a center air Chanel and the ghost cut gives me the cleanest front end of a yelp. What other kinds of cuts can you use with that? Has anyone else seen it and tried it out? I think it's helped me out or maybe I'm a little more confused about how to use a mouth call I don't know? Give me your feedback.
