Phosphor Bronze wound strings were introduced in the early Seventies and have become the most popular acoustic string. Phosphor bronze wire is made from approximately 92% copper, 7% zinc and 1% phosphorous. Phosphor Bronze provides nice highs and lows with pleasant subtle overtones. Phosphorous is used to help reduce tarnish and corrosion.

    Finally replaced the old strings on my Republic Singlecone resonator guitar. I usually use D'Addario but since these were recommended by Republic, I decided to try them and I'm glad I did. The guitar sounds cleaner, snappier and brighter, like a resonator should. They have a nice feel to them and are easy on the fingers (I finger pick everything). Not sure how long they will last, but I will definitely be using them on this resonator. Who knows, I might even try them on my Gibson J-45. Keep up the great work. Glad to help a local (Colorado) company.

    Great strings. They last better than any string I have tried. Great harmonics. Wouldn't use use any other.

    Just discovered the longest-lasting strings in the world!

    I burn through strings because of my finger acid (I guess) and have to change at least every month. When my Martin was serviced the tech returned it to me with a set of your strings...and it took me 7 months to figure I finally should get some new ones. Great value, great sound!

    When I picked up my Rockbridge Slope Shoulder Dred after having a pickup installed, I realized that things had changed. It sounded even better acoustically than it had before. Turns out the luthier had switched out the Elixer Mediums that I had on it for Curt Mangan Mediums without me knowing. The amazing thing is that I heard it immediately - and they never said a thing until I asked what had happened. These strings are oustanding.
