Retro strings offer a uniquely mellow, yet crisp sound that allows your guitar’s natural tonewoods to be heard. They are crafted with Monel, a solid nickel\/copper wrap wire - not nickel-plated - meaning there is no chance for defects in the plating to allow for corrosion. Martin’s proprietary wrap wire is naturally corrosion resistant and it is incredibly strong. Martin also employs a sophisticated winding process that controls the coupling between the core and wrap wire to maximize intonation.\u003c\/p\u003e","brand":"Martin","offers":[{"title":"Default Title","offer_id":10031337504804,"sku":"M07-41MM11","price":230000.0,"currency_code":"VND","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0020\/5111\/2996\/products\/M07-41MM11_1547632468516.jpg?v=1547632549","url":"https:\/\/www.sweelee.com.vn\/en\/products\/martin-41mm11-retro-acoustic-guitar-strings-custom-light","provider":"Swee Lee Vietnam","version":"1.0","type":"link"}
