For many years we made a "Parlor Guitar" which was modeled on an old Washburn guitar from the early 20th century.  This was a lovely guitar, but a very nice old Single 0 came through the shop, and we became quite enamored of the shape.  This is a similar size guitar with a somewhat different shape. It is lovely.  Still a small 12 fret guitar, so perhaps will not "take the market by storm," but it is a very sweet and balanced sound.  The customers who try them are uniformly surprised at how well much volume this guitar can produce.  Some options (such as a cutaway or an armrest) are not possible with this model, due to it's small size, but it is common (though by no means required) to make them with a slot head and a pyramid bridge.
