The Thomastik-Infeld DTKR39 Classic S (Classic N Rope Core) is an individual replacement low E (6th) string engineered specifically for classical and nylon-string guitars. Handcrafted in Vienna, this high-performance string features a highly flexible steel rope core wrapped in precision silver-plated copper flat ribbon winding, bringing acoustic-style punch, enhanced sustain, and crisp clarity to classical instruments without exceeding safe tension limits.

Designed to deliver supple, low playing tension that safeguards traditional classical fan bracing, tie-block bridges, and neck joints, the DTKR39 provides an ultra-smooth tactile feel with zero finger squeak and reduced fret wear. Australian classical, fingerstyle, and folk guitarists rely on genuine Thomastik-Infeld single strings to maintain spot-on intonation, balanced string-to-string projection, and dependable tuning stability.
