Thomastik AC112 12-59 Medium/Light Plectrum Acoustic Guitar Strings

Thomastik-Infeld AC112 Plectrum Acoustic Guitar Strings – 12–59 Medium/Light

Thomastik-Infeld Plectrum AC112 strings offer a uniquely refined acoustic voice with exceptionally balanced tension and smooth playability. Designed with a distinctive hybrid construction, the A, D, and G strings are flatwound, paired with a roundwound low E and plain steel trebles. Silk inlays at the ball end help control overtones and enhance tonal balance.

The result is a warm, focused, almost classical-inspired character that blends the richness of bronze with the smooth feel of fine jazz strings. The Medium/Light 12–59 gauge provides a strong, supportive low end while maintaining comfortable overall tension thanks to Thomastik’s carefully engineered tension balance.

These strings are especially well-suited for articulate flatpicking, nuanced strumming, and players seeking warmth, clarity, and controlled sustain. Their lower, evenly distributed tension can also make them a thoughtful choice for older or lightly braced guitars.
