Bought a Sumo on a whim to quiet the Impact a little more than the standard FX moderator. We got it home and did a little experimentation with the internals to make it quieter. It wasn't hard, just rearranging and replacing the materials did make a difference for the better. My son looked at me after we got done and said. "dad, it looks kind of plain". So with my son's help and direction, we fixed it. His idea, I just did what he suggested. It was an easy little project to do together, fun and we both like the end result...black and silver to match the Impact MKII.
