Listed only by Irwin, who says: An unusually soft form of Gedeckt, at 16', 8', or 4' manual pitch, made from either wood or metal pipes. It sounds almost pure fundamental, and can furnish this ground tone to such soft stops as the Echo Gamba, Dulciana, or Dolcan. It is a poor accompaniment stop because its pitch is not apparent even to listeners close to the organ.
