Does a double sided pot call need a tone board? For example, an aluminum top side with a slate bottom side, would the slate bottom work as the tone board or would you need a separate tone board in the middle of the call? If a separate tone board is needed, I'm guessing it should be positioned toward the top call surface? I'm thinking about trying to build a double sided call and I trying to get the call innards figured out.
Any info will be greatly appreciated.
Mine has a soundboard for each side.
