The Thomastik-Infeld JS112T Jazz Swing is a premier flatwound electric guitar string set crafted specifically for jazz archtop, hollowbody, and semi-hollow instruments. Handcrafted in Vienna, this medium-light .012–.050 gauge set pairs glassy-smooth, mirror-polished pure nickel flat ribbon windings on supple round steel cores with corrosion-resistant, tin-plated plain treble strings.

Unlike standard brass-plated versions, the tin-plated plain steel E and B strings of the JS112T deliver a traditional silver look, pristine top-end clarity, and superior resistance to sweat and humidity. Engineered to optimally drive carved archtop tops while maintaining Thomastik-Infeld's signature low-tension playing comfort, Australian jazz guitarists rely on this set for fatigue-free performance, zero finger squeak, reduced fret wear, and the rich, velvety tone that defines classic jazz tone.
