Get a replacement. It's new and shouldn't have a Crack. Every one of my three Cordobas cracked, two came with cracks. I don't know if it is coincidence, but they were all made in China. I haven't heard of anybody complaining about their Master Series guitars arriving with cracks yet, but they are made in the states. The conditions under which the guitar's are constructed, and the condition of the woods used, could be to blame.
