The Thomastik-Infeld JS113 Jazz Swing is the ultimate medium gauge flatwound string set engineered for archtop, hollowbody, and semi-hollow jazz guitars. Handcrafted in Vienna, this heavy-duty .013–.053 set pairs mirror-polished, pure nickel flat ribbon windings on supple round steel cores with brass-plated plain steel treble strings, delivering the authentic dark, smoky, and authoritative acoustic voice demanded by purist jazz guitarists.

Widely regarded as the industry standard for traditional carved archtops, the JS113 drives heavy spruce and maple soundboards with maximum acoustic volume, punchy fundamental warmth, and unmatched projection. Despite its heavier gauge profile, Thomastik-Infeld's supple round core construction ensures surprisingly low playing tension, minimal left-hand fatigue, zero finger squeak, and reduced fret wear across complex chord solos and bebop lines.
