D"Addario T4402 T2 Titanium guitar string is 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, you can substitute T2 Titanium Treble Strings for your current nylon strings with very little acclimatization. Designed for the classical player, D"Addario T2 strings will appeal greatly to flamenco, folk and other "non-classical" guitarists, as well.
