After almost two years of playing loud where I live I get a new amp & I finally get my first cop knocking on my door @ 9pm telling me he had recieved a noise complaint. Funny because I wasn't really cranking my volume THAT loud IMO, but **** happens & I gotta work with it. I would like to maybe get a "cheap"($20-50) attenuator if that would help, but what I would really like to do is sound proof the room a bit so less sound escapes outside if it won't cost too awful much money. It can cost more than $50, I just don't want to spend a shitload of money because I like to play somewhat loud & I have new V30 speakers so I want to break them in. I live in a manufactured home & the other houses are about 30 feet away from the front of my house where my jam room is. The room is very small, maybe something like 9x8 & it has one 3x2 window. If there was some way I could cut the bass by 50% or somewhere around there that would be great.
