The Thomastik-Infeld JR344 Jazz Roundwound is a premium 4-string electric bass set engineered specifically for 34" long-scale instruments. Bridging the gap between the supple warmth of upright-style flatwounds and the focused articulation of modern roundwounds, this set pairs a flexible round steel core with a finely wound, small-diameter nickel alloy outer wrap.

Renowned for its remarkably low playing tension, the JR344 set reduces neck strain on vintage and modern basses alike while significantly cutting down on finger squeak and fret wear. Bassists across Australia rely on the JR344 for its organic, woody low-end fundamental, singing sustain, and smooth, balanced feel across the entire fingerboard.
