Product DescriptionD'Addario's breakthrough EXP Coated Technology produces strings with the natural tone & feel of uncoated strings, with at least 4 times more life. EXP's allow a guitar's voice to ring true. With the creation of our new EXP Wire manufacturing facility we have invested in wire coating machinery which allows us to fully control and develop advancements in coating technology for wound strings that is second-to-none in the guitar string industry. The EXP Wire machine draws wire from rod, anneals, cleans, coats, cures and spools wire in one continuous process. This ensures our tight tolerances and specifications are adhered to. We test every spool of wire with a sophisticated digital micrometer which measures the concentricity of the coating thickness to 2/10,000 of an inch. We have successfully reduced the coating thickness by at least 50%, which allows the string to retain even more of its inherent brightness and natural uncoated tone, while maintaining EXP's renowned durability and long-life characteristics. You won't believe they are coated!
