Cleartone Electric Strings may have a coating of only one micron, but it' s more durable than coatings thousands of times its thickness. It won' t flake off with hard playing, nor will it feel slick or slippery to your touch. Super-high tension winding over a hex-core is used to maintain tuning consistency throughout your performance. EMP Treatment is then applied to all the strings (including plain strings) to ensure longest tonal life without compromises.
