12-16-24W-36-46-56 Lenth 43 inches. 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. It took several years of trial and error to develop a proprietary string coating that resists tarnish and corrosion without compromising tonal quality. Phosphor Bronze provides nice highs and lows with pleasant subtle overtones. Phosphorous is used to help reduce tarnish and corrosion.

    Acoustic guitar strings

    The best strings I've ever played. They feel like they are lighter Guage than they are. I have switched to Curt Mangan strings now and I play them exclusively on my acoustic and electric guitars.

    Great strings, coating does not affect tone. Don't play bluegrass but bought to increase bottom end and they sure did! Now on my four guitars!

    Best strings ever!

    Best strings ever, tried em all, these hold up, with lots of both brightness and warmth. You've gotta try them to see what I mean, it's not a plastic coating, it's Curt's own special fusion process. Try them. It's worth a little extra. We use only Mangan strings on all our guitars and basses, they are the best.
