Has anyone disassembled and reassembled their mountain banjo? I want to show someone how it all goes together and specifically show them the tone ring. I might even try swapping the tone ring to another material to see how it affects the sound. My concern is whether taking it apart will mess up the head tension when it goes back together, even if I stick with the same tone ring. If anyone has tried opening it up, can you please reply about whether you needed to redo the head as a result?
