Martin employs a unique process that ensures improved coupling and consistent gaps between the round core wire and the wrap wire which results in superb intonation. A pure nickel wrap allows Titanium strings to remain naturally corrosion resistant and hold their tone for an exceptionally long time. Furthermore, Titanium core wire is round, not hex, for enhanced flexibility. The plain strings are also unique to this product, as they are cryogenically treated stainless steel. The cryogenic treatment protects the string and brings out more brilliance in the stainless steel.
