Description Product Description This D-28 Authentic 1937 is the real deal. There are three big standout features that make this guitar sound so exceptionally rich and broken in. The bracing pattern is the same as what you'd find on a real 1937 D-28: forward shifted hand-scalloped X-bracing. This allows the top to vibrate more freely than other bracing patterns and naturally sculpts the low-end, resulting in a louder, clearer guitar. The dovetail neck joint with mahogany blocks does incredible things to the sustain and also makes for a stable neck that isn't going to give you any trouble. Lastly, the top and braces have been treated with Martin's new Vintage Tone System. This is a torrefaction system (fancy term for advanced wood baking process) that makes the wood think it's nearly 100 years old without compromising strength or durability. You'll really notice it in the sensitivty of the response. At extremely low volumes, the guitar still picks up everything your fingers do, something I'm used to feeling only on very old guitars.
