Martin 80/20 Bronze Custom Light Acoustic Guitar Strings:
Martin M175 acoustic guitar strings are precision made with 80/20 Bronze alloy wrap wire. 80/20 Bronze alloy is 80% copper and 20% zinc. This combination yields a very brilliant (bright) tone when new, that softens and mellows with a little age and playing. Martin strings produce that classic American acoustic six-string guitar sound that emerged in the late 1960's, and became the standard and preferred tone for the following decades. Martin acoustic guitar strings have withstood the test of time, and now the M175 custom light acoustic set will continue the tradition, in all genres.
