Description
The Thomastik-Infeld JS113 is the legendary flatwound jazz guitar string in its medium incarnation, found on the guitars of countless jazz icons over decades of studio and stage work. Unlike ground wound or compressed wound sets that mimic the feel, this is a true flatwound — polished nickel wrap wire drawn over a round core, delivering the glassy-smooth feel and mellow, articulate voice that defines traditional jazz tone. The plain E, B, and G are brass-plated steel; the D, A, and low E are nickel flatwound.
Designed specifically for semi-acoustic and acoustic jazz guitars, the JS113 delivers the perfect balance of fundamental to overtones for the genre: warm bass definition, bell-like treble clarity, and a silky transition from open chords to bar chords. Tonal life is remarkably long — many players report that the sound actually deepens and matures with age. At .013-.053, this is the heaviest gauge in the Jazz Swing line — the traditional big-string choice for archtop players who want maximum acoustic projection, firm chord-comping authority, and the full-bodied low end that suits large-body hollowbodies and semi-acoustic jazz guitars best. Made in Vienna to Thomastik-Infeld's century-old standards.
