I live in a townhouse. My amp is in the lower level, which has a walk-out basement with sliding glass doors. My son is down there right now playing my bass and I am on the middle floor typing this. He's not really playing that loud or agressively but my rear end is getting a massage from the sound vibrations travelling upstairs. Amazing. Now I'm afraid that my neighbors are going to raise holy hell with me as I'm learning how to play. Short of major renovations, are there any tips you can offer to somehow deflect the deep sounds???
