Thomastik JF344 Jazz Flat Wound Electric Bass String Set (43-100)

The Thomastik JF344 Jazz Flat Wound Electric Bass String Set delivers the legendary flatwound tone Thomastik-Infeld is renowned for among upright bassists, now engineered specifically for electric bass guitar. This medium-gauge long scale set features gauges .043, .056, .070, and .100 inches for standard 34-inch scale basses. The construction centres on a highly pliable steel round core wrapped with silk inlay, then finished with a true ribbon flatwound outer winding made from a proprietary nickel alloy.

Each string in the JF344 set uses nickel flat wound roundcore construction to produce exceptional depth and enhanced fundamental response. The G string (.043"/1.09mm) maintains 37.03 lbs tension, while the D (.056"/1.42mm) holds 37.47 lbs. The A string (.070"/1.78mm) sits at 31.30 lbs tension, and the E (.100"/2.54mm) delivers 34.39 lbs. The silk inlay beneath the ribbon flatwound outer layer creates a playing feel and tonal character distinct from conventional flatwound designs, offering reduced finger noise and a warm, articulate voice across the frequency spectrum.
