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.
