Length: 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.
I wanted to give these strings a try because of the supposed higher quality wire, tighter winds etc.... The factory tour got my attention. And being made in the USA was a plus. Had them installed on my Martin for a week now and thus far, great sound, note definition was a little muddy with other strings so these were just t the ticket. Now to see how they do over time.... Some strings sound great new, these certainly do..but after a few weeks, other strings go muddy on this guitar. I will let you know...
