Description

D'Addario was the first to use Phosphor Bronze in acoustic guitar strings back in 1974. Today, Phosphor Bronze is played throughout the world and considered to be the standard in acoustic strings, thanks to its beautiful sonic balance and tonal warmth. Our pioneering Phosphor Bronze acoustic guitar strings are precision wound with phosphor bronze wrap wire over a high-carbon steel core, providing tonal versatility suitable for all acoustic styles and musical genres. From the Manufacturer EJ39, D'Addario's medium gauge 12-string acoustic guitar set provides heavier tension resulting in a bolder, more resonant acoustic tone with higher resistance for heavy strumming or aggressive fingerpicking.Phosphor Bronze was introduced to string making by D'Addario in 1974 and has become synonymous with warm, bright, and well balanced acoustic tone. D'Addario Phosphor Bronze strings are precision wound with corrosion resistant phosphor bronze onto a carefully drawn, hexagonally shaped, high carbon steel core. The result is long lasting, bright sounding tone with excellent intonation.D'Addario, the world's largest manufacturer of musical instrument strings, is known as The Players Choice with a reputation for unsurpassed quality and consistency. D'Addario's innovative,packaging reduces waste and provides protection from corrosion. All D'Addario strings are manufactured in the U.S.A. using proprietary, digitally controlled, state-of-the-art machinery for unmatched performance, set after set.

  • These are great for the price
Style: 1-Pack Size: Medium, 12-String, 12-52
These are great for the price. I usually prefer Elixir strings but these give off a great bright sound and have held up well against my harder than average strumming.

  • My Guitar is Happy
Style: 1-Pack Size: Medium, 12-String, 12-52
I am mostly a strummer and I am a bit hard on strings which is why I went with the mediums. I have used D'Addario before but these Phosphor Bronze seem to have a warmer feel to them and the sound is great. I have paid much more then this for a 12 string set and received much less quality. These will be my go-to strings from now on. ... show more

  • Good gauge strings at a good price
Style: 1-Pack Size: Medium, 12-String, 12-52
Finally found a decent gauge set of strings that are affordable. Good sound without the tinniness of the light ones that are usually available. Highly recommended

  • Buy these Medium Strings
Style: 1-Pack Size: Medium, 12-String, 12-52
I had the same brand but the light ones. I thought they were too light for my 12 string guitar. I decided to go to the mediums and it made it sound deeper. That is what I was looking for. Every guitar might sound different so I am saying for me and my D'angelico 12 string, these mediums are good.

  • Great strings from a great local manufacturer
D'Addario makes some of the best guitar strings I've ever played. The string are warm and bright, with great sustain, on my 12-string acoustic. The company is based on Long Island, New York, where I live, so I am proud to support the "local economy".
