Thanks again for your comment. I called Gibson and asked them about the yes it is chamebered. Actually the classic is chamebered the same for the single cut LP classic. The Standard has the solid body which is a AAA wood. On the other hand they don't make the standard DC left handed.
I had a Dean not a hardtail though, and have a bad experience with their customer service. My guitar had some cosmetics and electrical problems out of the box, it took more than a month to get it replaced. They hesitated about replacing the guitar.
