D"Addario T4601 T2 Titanium Guitar Strings are crafted from a dense monofilament material that has an attractive, translucent purple hue. T2 strings have a polished, smooth feel analogous to nylon, but with a slightly brighter tone and increased projection. As a result, the T2 Titanium Treble Strings may be substituted for current guitar strings with little player acclimatization. Designed for the classical guitarist, D"Addario T2 strings will appeal greatly to flamenco, folk and other "non-classical" musicians, as well.
