Plugged in my new Markbass TA503. played around on it for a bit. practiced my arpeggios. Walked out of our "music room" and wife stated if you're going to practice you have to take the pictures off the wall! They were all rattling. The problem is that I was not playing loudly, nor do I care too. BUT the new amp is way more than the PF350 I was using. The room is also a problem. I have to be careful or the paintings on the other side of the wall aren't the only things that rattle. So I figured it's time to work on the music room. But I'm not sure where all to start. I figured some good heavy rugs to start with. I've heard hanging curtains on the wall just kills the highs. (my wife uses the room to practise her clarinet as well.) Any suggestions. I've included a picture to let you know what I'm working with. OH and cost IS a factor!
