CS-12 Natural is the classical guitar from the "Studio" series by Eko Guitars with a Sitka Spruce top, laminated Mahogany back and sides, Mahogany neck and Resin fingerboard. Within the Studio series it certainly represents a very high performance instrument thanks to the choice of woods, ideal for those who are beginning their guitar study, but also for the musician who, at an affordable price, is looking for a reliable "6-string" with generous volume.
