Great questions Scott. I'm not trying to build a slate call that sounds like a glass call, what I'm trying to get is a slate call that reacts the same as a glass call. If you run different strikers on a glass surface, you get a big difference in sound and how the call plays to each striker, with a slate surface you get a change but it's not as drastic as it is on a glass, so what I'm in search of is combos that will give a slate a more drasic change just like a glass surface does. Your strikers are the fine tuning device of a pot call, just like a tuning fork. If you pinch a striker tightly you get a higher pitch out of the call, if you hold it loosely you get a more raspier sound out of it. On a glass surface you really hear the difference, but not as much on a slate surface. That is what I'm looking to change, so the call reacts the same no matter what surface you've got in it. I'm not sure if the spalted maple had that much to do with how the call reacts? I'll find out more as more get build out of different woods. The call is exactly the same size as all my other calls. The sound holes have a lot to do with the sound of a call, if your sound holes are to big, you loose the echo out of the pot and it weakens the bottom of the call causing it to vibrate a lot more then it would with a smaller hole, just like if the bottom of the pot is too thin, that has a lot to do with the design of your pots. Just like running a thin or thick lid does on a box call. Most people really like the sound and ease of play of a slate surface, but you are somewhat limited to the sound you get out of the call, what I'm trying to do is find different combos that causes a call to react differently to however you play it so you get a more unlimited sound out of a slate call.
It's been fun [:D].
