The hallmark of Cort’s Gold series acoustic guitar is the Aged to Vintage (ATV) treatment that cures the Sitka spruce top to deliver the full and open tone of a vintage guitar, from day one. ATV acts as a torrefaction process, giving the Gold-D6 a big, open tone that’s bright, yet natural with a strong and warm midrange that’s reinforced by the solid Mahogany back and sides. A sonically enhanced UV finish protects both the instrument and tonal quality. Cort Gold D6 NAT Dreadnought Acoustic Guitar
