Before using Martin Acoustic strings, I used Elixirs. While Elixir makes great strings that are long-lasting, I think that Martin Strings have the brightest, warmest tone for acoustic guitars.
Every musician who likes the sound of Acoustic Guitars knows how important Martin & Co is on this area. These strings are incredibly long-lasting with a vibrant and powerful tone. They are the perfect pair for a Martin Guitar but they can also be used with other guitar brands to add its unique steel sound to the instrument.
