Description
The Thomastik-Infeld JS112 is the legendary flatwound jazz guitar string in its medium-light 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 JS112 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 .012-.050, this medium-light gauge offers a firmer, more traditional archtop feel with added low-end weight and chord-comping authority — a natural fit for players who want more grip under the pick than the lighter JS110 and JS111 sets. Made in Vienna to Thomastik-Infeld's century-old standards.
