.Gibson initially called the new Style O “Special Grand Concert,” but it was the only grand-concert-sized guitar (16″ wide) in the line. In 1911, when a more conventional 16″ guitar (the L-4) appeared, catalogs began referring to the Style O by the name most collectors call it today – the Style O Artist.

The Style O had a radical appearance compared to other guitars made in 1918, and that would continue throughout the model’s production period from 1908 to 1925. Not only was it radical in appearance, it was functionally very modernistic and innovative. Whereas most guitars of the period had necks with 12 frets clear of the body, the design of the Style O’s upper treble bout provided 15 frets clear of the body. Although it did not have the circular or cupped shape of the cutaways were familiar with today, it functioned the same, allowing easy access into the higher register.
