The M170 appeared on our recommended list for Extra Light Acoustic Guitar Strings from December 2021 until June 2022 when it was removed due to there being more highly rated sets of strings available.

Then in November 2022 it had high enough ratings to go back on the list where it is today.


With their long history as a premiere acoustic guitar manufacturer, C.F. Martin & Co. certainly knows how to develop and mass produce good quality strings. The Martin M170 Originals is their best rated extra-light gauge set for acoustics, designed to be easy on the hands, while retaining their signature woody tone.

This set features 80/20 bronze windings that work well with various musical genres, with each string undergoing production and quality control that meets Martin’s high standards.

With its 0.010″ high E and 0.047″ low E string, this set is expected to sound clean and bright. It is a good compliment to naturally boomy sounding acoustic guitars.

When it comes to acoustics, it’s hard to go wrong with Martin. This is definitely well worth checking out if you’re looking for a good quality extra-light gauge set.


  • Gauge: Extra Light (.010 to .047)
  • Material: 80/20 Bronze
  • Coated: No
Although these were previously on our recommended list, there are now more highly rated options available which you can see in our guide to The Best Acoustic Guitar Strings.
