Thomastik-Infeld AC111 Plectrum Bronze Acoustic Guitar Strings (11–50)

The Thomastik-Infeld AC111 Plectrum Bronze set is crafted for acoustic guitarists seeking a warm, vintage tone with a smooth feel and low overall tension. With gauges .011 / .014 / .019(F) / .027(F) / .036(F) / .050(R) (where “F” denotes flat-wound and “R” denotes round-wound), the flat-wound A, D and G strings combine with a round-wound low E to preserve articulation and sustain. The brass-coated plain steel strings and silk-inlayed wound strings deliver a rich, focused sound especially suited for older instruments, recording, or refined performance settings.
