1930 National Style 0
Here is a 12-fret Style 0. This one has a steel body. The early production of Style 0s were made of steel. They later switched to brass. The steel just didn’t take the nickel plating as nicely as brass. So most Style 0s were made of brass. But, the steel ones sound great! The tone little less elegant than the brass body, but there is a different ring to to the note and nice sustain that comes from the steel. Style 0s have maple necks and maple fretboards dyed black to look like ebony (they called it ebonized). On this one, the tuner slots on the headstock are squared off on the top. Only very early Style 0s and metal-body Triolians had slots like this.
