I'm experimenting designs for slate and glass calls. In the course of doing this, I'm making a lot of calls, most of which are not up to par sound-wise. I've been finish sanding and applying finishes to these calls, which as you know, is almost half the time it takes to make a call. I know sanding and finishes affect the sound of a call, but my question is this: Can I make experimental calls to get the sound I want without sanding and finishing, and then when I get some designs I like, sand and finish, or is the sound between finished vs. unfinished calls going to be too different?
