Overview
This model captures the vintage slope-shoulder dreadnought sound—warm, woody, and balanced—with premium tone-woods and solid construction. A great alternative to much higher-priced American-made guitars.
A Bit of History: The slope-shoulder dreadnought design traces back to early 1900s instruments built by Martin for the Ditson Company in Boston. The “Extra Large” body shape eventually became known as the Dreadnought, setting the standard for modern acoustic guitars.
