Summer NAMM 2019: D’Addario develops XT strings with cutting-edge tech

Featuring high carbon steel cores, the brand’s popular alloys and extended lifespan treatment.

D’Addario has introduced XT strings, the brand’s most technologically advanced strings thus far. These will be available in six categories: electric, acoustic, classical, bass, mandolin and banjo. 

A product of D’Addario’s R&D work, the new strings feature a combination of high carbon steel cores, the brand’s most popular alloys as well as extended lifespan treatment. The last of these is touted to improve on three factors – break resistance, pitch stability and sustained performance – while still retaining the tone and feel of uncoated strings. 


The new strings have impressed Grammy-winning jazz guitarist Pat Metheny, who commented: “I’m usually more focused on the notes rather than the strings. But with XT, there’s an evenness and clarity that really jumps out.”

Available in September at a range of list prices starting from $9.99. More info at
