12-16-24W-32-44-54 43 inches. 80/20 Bronze wound strings are often called old-school, vintage and/or bright bronze and were the most popular alloy used to make acoustic strings until the introduction of phosphor in the early Seventies. 80/20 bronze wire is made from 80 percent copper and 20 percent zinc. 80/20 Bronze provides balanced highs and lows with a slight increase in mid-range that seems the make the notes "cut-through" a little more. It took several years of trial and error to develop a proprietary string coating the resists tarnish and corrosion without compromising tonal quality.
These are the finest coated strings I've ever used and are quite possibly the best strings of any kind I've ever used on an acoustic guitar that wants light gauge strings. I've also used the medium gauge on other guitars and they are equally stupendous. They feel, sound, and play like the best quality non-coated strings yet last far longer. They stretch and maintain tone faster than nearly any other strings I've ever slung onto an acoustic machine. Love 'em. Absolutely love 'em.
