Martin M1700 Marquis 12-String Bronze Light Acoustic Guitar Strings
Martin Marquis M1700 strings produce a bright, ringing, and powerful 12-string acoustic guitar tone, thanks to 80/20 bronze alloy windings (80% copper and 20% zinc), which is well know for its brilliant tone. They also feature a silk wrap at the ball ends, which reduces wear on bridges and bridge plates.
Martin M1700's are a 12-54 "light" gauge set, which is easy on the fingers, making chords a snap. They give you the classic 12-string acoustic guitar sound.
