The Thomastik-Infeld DTJS23 Jazz Swing is an individual .023 gauge wound D (4th) flatwound replacement string engineered 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 rich acoustic warmth, velvety fundamental punch, and articulate overtone balance that define the benchmark Jazz Swing series.

Whether used to replace a broken string or to craft a tailored custom-gauge setup, the DTJS23 provides remarkably supple left-hand feel, minimal finger squeak, and reduced fret wear. Australian jazz guitarists and archtop players rely on genuine Thomastik-Infeld single strings to preserve optimal string-to-string tension, precise intonation, and authentic vintage jazz voice.
