Examples
Flatback render Flatback mandolins use a thin sheet of wood with bracing for the back, as a guitar uses, rather than the bowl of the bowlback or the arched back of the carved mandolins.
Double top A variation of the flatback has a double top that encloses a resonating chamber, sound holes on the side, and a convex back.
Like the bowlback, the flatback has a round sound hole.
