A Martin Replacement String Designed for Demanding Guitarists
The Martin M11HTT SP in plain steel is an acoustic guitar string sold individually, perfect for emergencies during rehearsals, studio sessions, or on stage. Part of the Martin Authentic Acoustic family, it follows the brand's approach: a very robust core, reinforced by a tin plating on all 6 strings to improve corrosion resistance, and manufacturing focused on a reliable sound over time. Note: while the Authentic Acoustic range is also available in 80/20 Bronze and 92/8 Phosphor Bronze versions for wound strings, this reference corresponds to a single SP plain steel string in gauge 11, ideal for completing a set, maintaining consistent gauge, or fine-tuning a custom setup.
