The “RS” is code for “Roy Smeck,” who was the biggest guitar hotshot of the 1930s and endorsed Gibson 12-fret Dreadnoughts with big meaty necks sold for Hawaiian-style playing. Richard Hoover and the SCGC crew wisely skipped the big neck but kept the mahogany back and sides. The colorful band of marquetry around the perimeter of the top is a nice touch, but not a feature of the original Roy Smeck models, so this is no slavish reissue. Part of what gives these guitars such a distinctly different sound is that the sides don't have the same taper from endblock to neckblock as the later models, and the deeper upper bout gives the guitar an even greater internal air volume. It's hard to describe the difference, but it's an airy open tone that still has plenty of punch (and of course plenty of volume).
