The Thomastik-Infeld DTJS20 Jazz Swing is an individual .020 gauge wound G (3rd) flatwound replacement string crafted specifically for archtop, hollowbody, and jazz electric guitars. Handcrafted in Vienna, this single string pairs a glassy-smooth, mirror-polished pure nickel flat ribbon winding over a supple round steel core, delivering the iconic mellow warmth, deep fundamental punch, and clear overtone balance that make the Jazz Swing series the global benchmark.

Ideal as a direct replacement for worn strings or for building tailored custom-gauge sets, the DTJS20 provides an exceptionally smooth left-hand feel, zero finger squeak, and reduced fret wear. Australian jazz guitarists and archtop players rely on this genuine Thomastik-Infeld wound G string to maintain spot-on chord intonation, optimal soundboard vibration, and balanced string-to-string tension across the fretboard.
