In Bristol, TN, the Grand Guitar, modeled after a Martin guitar, is three stories tall and 70′ long. It was built in 1983 and originally housed a music store. It was later used as a radio station and country music museum with unusual instruments and Porter Waggoner outfits. The building was vacant in 2001 and deteriorating. In 2004, it reopened briefly as the Joe Morrell Grand Guitar, a music museum. I believe it is still vacant as of 2009.
