## Description

From the manufacturer The Authentic Acoustic Range Superior Performance SP These strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. We start with our highest tensile-strength core wire, then tin-plate it on all six strings for added corrosion resistance; because what you don’t see matters! When coupled with our highest quality wrap wire you get consistent true tone that you can count on song after song. Available in 80/20 Bronze and 92/8 Phosphor Bronze. Martin Authentic Acoustic SP strings offer excellent tuning stability, corrosion resistance and great playability. Marquis Silked Martin Guitar knows a thing or two about pampering valuable instruments. If you’re looking for some extra protection for your fine guitar, Authentic Acoustic Silked strings are the right choice for you. We’ve added a soft silk wrap to the ball ends of our Authentic Acoustic strings to prevent wear and tear on the bridge and bridge plate as you play. Our silk wrap puts a comforting layer of protection in place every time you change your strings. Available in 80/20 Bronze and 92/8 Phosphor Bronze. Martin Authentic Acoustic Marquis Silked strings offer thread wrapping for bridge protection, corrosion resistance and excellent tuning stability. Lifespan 2.0 Martin’s next generation Lifespan 2.0 strings are engineered using a new, patented technology only available from Martin. This technology was developed to protect the core wire and the wrap wire to prevent corrosion without compromising tone – the single most important attribute of the guitar strings. Authentic Acoustic Lifespan 2.0 strings look better, sound better, and feel better, providing a smooth playing experience that reduces finger drag. We invested two years developing our next generation Lifespan 2.0 strings to ensure they will sound better, longer than any other extended-life string on the market. Available in 80/20 Bronze and 92/8 Phosphor Bronze.

Review: Best I’ve ever used! - Just gave my Epiphone a full clean and restring with these, tuned up and hit a chord and I’ve never heard my guitar sound so full and resonate. I can’t comment on their longevity, but I would happily pay for new strings every month to have my acoustic sounding this good. (Acoustic is an epiphone J45 studio, formally known as the AJ220) I also use a Fender sound hole pickup (the wooden one), which I highly recommend for anyone wanting to turn their acoustic into an electro acoustic. There’s none of that horrible electro acoustic twang when plugged in, instead it sounds like a mic’d up acoustic. Only downside is that it’s quiet than a normal electro acoustic, but thats an easy fix with more volume, so I’ll take that over the horrible electro twang any day.
Review: Good value for money! - Bought these to restring an electro acoustic Tanglewood being used by a new learner. These are good value for money! There is a marked difference in the sound quality with these when compared to the original strings, a nice rich sound!!! And they come in a pack of 3 sets, so definitely value for money!

### ⭐⭐⭐⭐⭐ Best I’ve ever used!

### ⭐⭐⭐⭐⭐ Great picking strings, the older the guitar the better they sound.
*by S***N on 11 July 2023*

Great picking strings, the older the guitar the better they sound. New guitars sound tiny (unless they are hugely exensive), older guitars from the 70's have nicely matured wood and the strings sound great. You can really play gently and it sounds great.
