Martin Guitars have consolidated their gargantuan range of acoustic strings into three distinct ranges: Superior Performance, Marquis Silked and LifeSpan 2.0. All three ranges share the same tin-plated, high-tensile steel core and option of 80/20 or Phosphor Bronze wraps in various gauges.
“We have taken our market leading strings and made them better in every way. They look better, they feel better, and they sound better. Period. And with three versions to choose from, any player can find the ideal strings for their acoustic guitar.” - Martin Guitar
Three distinct ranges:
Superior Performance - Martin Authentic Acoustic Studio Performance (SP) strings are engineered with the performer in mind, and they will always stand up to rigorous practice and performance schedules. The core is Martin's highest tensile-strength which is then tin-plated for corrosion resistance (including the non-wounds). The cores are then wrapped with Martin's highest quality 92/8 Phosphor Bronze or 80/20 Bronze wire.
Marquis Silked - Martin Authentic Acoustic Marquis strings are designed specifically for pampering your guitar. The Marquis strings are built like the Superior Performance strings but with the addition of a soft silk wrap added to the ball ends of the strings to protect the bridge and bridge plate from the wear of steel when playing. Show your guitar some love.
LifeSpan 2.0 - Martin Authentic Acoustic LifeSpan 2.0 strings are engineered using Martin's own patented technology developed to protect both the wrap wire and core wire of the string. This barrier prevents corrosion and oxidisation which could comprise tone and life. Martin LifeSpan 2.0 strings stay looking, sounding and feeling better for longer than normal strings providing a smooth playing experience. Think Superior Performance with greater endurance.
