6 STRING ACOUSTIC GUITAR 'The new Gold-OC8 was developed to meet the demand for premium guitars from guitarists looking for a comfortable OM size body with 43mm (1 11/16”) nut width. The hallmark of Cort's Gold Series is the Aged to Vintage (ATV) treatment that allows the solid Sitka Spruce top to cure and open more over time. The ATV acts as a roasting process, giving the Gold-OC8 a big, open tone that is bright but natural with a strong, warm midrange that is reinforced by the solid Pau Ferro on the back and sides. .
