Thank you for viewing. This is a MARTIN D-16GT, purchased new around 2013. I am selling it because I rarely use it anymore. Based on the serial number, it appears to be a 2012 model. Approximately 80% fret life remaining. Truss rod has not been adjusted. A strap pin has been added to the neck end. There are many scratches and other signs of use. No claims and no returns accepted. - Top: Sitka Spruce - Back and Sides: Mahogany Please see the Martin website for detailed specifications. https://www.martinclubjp.com/guitars/discontinued_models/D-16GT/
