12-16-24W-32-42-53 43 inches 80/20 Bronze wound strings are often called old-school, vintage and/or bright bronze and were the most popular (only) 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 increased in mid-range that seems to make the notes cut-through a little more. It took several years of trial and error to develop a proprietary string coating that resists tarnish and corrosion without compromising tonal quality.
These strings are the best! I have a 2000 Taylor 814 & it tends to get boomy with the wonderful low end, especially when plugged in. These solve that problem as well as giving a terrific balanced sound. I'm on my 2nd set & I'm not sure how long they really last. I expect them to last 4 to 5 weeks. I play 1 to 2 hours a day. Exceptional for comfort & recording.
