This Martin JC-16re Aura is in great condition. There are some very lite signs of use on the pick guard and back and one scratch on the side of the guitar along the bottom, but barely noticeable. I've included a picture of that defect. But overall a great piece in great condition. The action has not been modified, it is set to factory settings. This guitar comes with the original Martin case as shown in the pictures. It features the Aura effect option in the pickup which allows you to play through an amplifier with your natural unaltered tone but also gives you the option to modify your tone by choosing one of 6 settings. These settings were created during the manufacturing of this guitar by recording the  guitar through different high end condenser  microphones  and programming these tones into the eq.  You can choose any one of these tones or you have the option to blend your natural tone with one of these settings  to create some amazing  sounds. The guitar also features  a feedback eliminator, chromatic tuner, and adjustable eq.
