Not sure if this is the best place to ask this question, but... I am in the process of moving to a new house, in a new subdivision, where the houses are considerbly closer together than my current home. THe plan is to make one of the bedrooms into a 'guitar room' of sorts. I want to soundproof this room to a degree where it will not bother the neighbors. Anyone have tips on this, or links to a type of acoustical foam or something I could line the room in? Im not planning on whipping out a non-master Marshall cranked to 11, but I would like to comfortably play my 20w combo and/or stereo at a decent level. Any ideas would be appreciated!
