AUTHENTIC ACOUSTIC
Superior Performance
Superior Performance strings are designed with the performer in mind and will always survive rigorous practice and overwhelming performance schedules.
Our most tensile core is tinned on all 6 strands for added corrosion resistance. Because invisible, is important.
And when combined with our top quality windings, youll get a consistent "real tone" that you can experience every song plays.
The strings in this series provide excellent tuning stability and corrosion resistance (rust resistant) and excellent playability.

With the 2018 Martin string lineup renewal, the "ACOUSTIC SP" series of Martin Acoustic Guitar Strings is passed down to this AUTHENTIC ACOUSTIC Superior Performance series.
Punched, warm, balanced sound. MA540 PK3 is the successor to Martin MSP-4100 PK3. This is a 3-pack set of MA540.
