There is apparently a spoon projecting from the front face = of the jack just above the articulation that contacts its very own = regulating screw button sitting above the standard one for the jack = tongue. After thinking about it, I sort of theorized that this feature = changes the jack's relationship to the underside of the knuckle by = altering the angle that the jack top faces the knuckle after = escapement--perhaps making return to playing position easier(?) I've = never seen or heard of this beast, and was hoping someone could shed = some light on it.
