Martin has made some changes to their string product lineup, and their same fantastic quality strings are now available in three distinct options:
1. Authentic Acoustic Superior Performance sets. These great acoustic sets have been designed to sustain tuning stability, resist corrosion by having tin plating on all strings, and they have high tensile steel core wire that is the best in the industry.
2. Authentic Acoustic LifeSpan 2.0 set. Authentic Acoustic sets with LifeSpan proprietary coating to provide longer life without sacrificing tone. Great strings!
3. Authentic Acoustic Marquis Silked sets. Similar to the old Marquis sets, these have silk wrapped Authentic Acoustic strings to protect the bridge of your guitar. We don't have these in stock yet, but expect them soon.
