Could you explain in more detail what it looks like installed, what it's made from, does it stretch across the head or just muffle the edge? Just one edge? All I know now is they may rattle, so OK that suggests metal. Is it a round pad? Rectangular pad? A strip? Is it adjustable or just on or off? What color is it? Who is Jimmy Pratt? Is he still alive? Am I annoying you enough yet?
