This Style U is the most common model of all Gibson harp guitars, and this particular model from 1917 is its most common configuration—10 sub-bass strings (tuned chromatic), and six standard strings (tuned to standard tuning). Earlier harp guitars, some of which were built with 12 sub-bass strings, are considered quite rare and hard to find in good condition. This Style U model measures approximately 45.5” in length, 18.75” in width, with a rim depth of 3.5”. Its scale length is 24.75”, and it weighs approximately 9.5 lbs. In 1917, its list price was $248.21—a pretty hefty price tag for any instrument in its day.
