I guess what he wants is to tame down the noise his savage makes because people are complaining when he plays it in his neighborhood, particularly the guy he said who came out of nowhere and wants to hit his savage with a sledgehammer to silence it because it was making a lot of noise that they were not used to. I hope I am correct.
