Premium coated strings for acoustic guitar from D'Addario XT series. An extended lifespan treatment on every string in the set preserves the natural tone and feel of uncoated strings. Strings last at least 4 times longer than traditional uncoated strings without sacrificing the tone or feel that players know and love.

Made using a high carbon NY steel core and fusion twist ball end, XT strings are incredibly break resistant, hold seriously strong tuning stability and protect against corrosion.

Phosphor Bronze is a 92% copper, 8% tin alloy with traces of phosphorous. These produce a naturally warm, smooth tone and work well for any type of playing technique.
