Got it about a week ago and loved the sound. It arrived well packaged and there was no physical damage. But when I turned the bass up and hit the E string, it had a terrible rattle. Instead of contacting service, I decided to remove the back off of the cabinet and tightened all the screws internally as there were a number of them that were not snug. I attached the back cover and tightened these screws snugly also. This took care of the problem. I hope yours doesn't have the same issue, but if it does you might try this.
