This Iris Guitars DF Slope-shoulder in Natural pairs two of the most coveted tonewoods in acoustic building: East Indian rosewood back and sides for deep, complex low-end and shimmering overtones, and an Adirondack spruce top left free of toner, so the wood is allowed to age and darken naturally into its own character over years of play. The slope-shoulder body shape softens the punch of a dreadnought into something warmer and more nuanced, while the comfortable C/D mahogany neck and 1-3/4" nut give players a familiar, easy feel under the hand. Details like the tortoise binding and matching long tortoise pickguard, rosewood bridge, and vintage-style open-back tuners with cream buttons round out a genuinely premium build from headstock to heel. This is rosewood-and-Adirondack tone at its finest in a brand-new instrument, ready to open up for decades, and it comes home in its included TKL hardshell case.
