Cleartone Hybrid electric guitar strings have a coating of only one micron that'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. Cleartone strings feel and sound like an uncoated set yet last a really long time, giving you what your playing demands: uncompromised tone with an incredible lifespan. Cleartone guitar strings feature EMP (enhanced molecular protection), a unique, micro-thin coating that protects your strings against corrosion. EMP Treatment is applied to all the strings including the plain strings.
