Description
The Thomastik-Infeld JF346 is the 6-string long-scale version of the legendary Jazz Flat Wound bass line — the electric bass answer to Thomastik-Infeld's iconic Spirocore upright bass strings, and widely regarded as the reference standard among true flatwounds. The construction draws directly from the upright tradition: a highly pliable round steel core is wrapped with a silk inlay, then finished with a true ribbon flatwound outer winding in a special nickel alloy. The silk inlay increases flexibility and gently damps excessive overtones, while the round core lets the string vibrate freely with no preferred motion axis. Together these elements deliver an incredible depth of tone and enhanced fundamental unavailable from any other flatwound.
Voiced for the warmth, articulation, and dynamic sensitivity of an upright bass in an electric format, the JF346 is a longstanding favorite of 6-string players who want organic, focused, minimally-fingered tone rather than the clank and sustain of a roundwound. At .033-.136 in long scale, the set adds both a wound .033 high C and a generous .136 low B — the latter noticeably heavier than typical B-string gauges — compensating for the naturally lower tension of flatwound construction to keep both extremes tight, focused, and articulate. Silk-wrapped ends at both the ball and tuner sides secure the windings for long-term stability. Made in Vienna to Thomastik-Infeld's century-old standards.
