"Everyone knows that coated strings last longer, and uncoated strings sound better. There is a Tone compromise. Cleartone Treated Strings feature a protective film called EMP – Enhanced Molecular Protection. This treatment helps prolong tonal life without sacrificing feel or sound. At one micron thin, it is up to one thousand times thinner than coated strings. In fact, EMP treated strings last as long or longer than other string brands on the market, but feel and sound like an uncoated set. This gives you exactly what you always wanted - killer Tone with an incredible lifespan. Let’s face it, changing strings is annoying, but throwing on a virtually dead set to begin with is much worse. Also, unlike coated strings, the EMP treatment works equally with both acoustic and electric strings. EMP bonds to the molecules in the metal so during hard strumming it doesn’t feel slippery and never flakes off. Cleartone Strings feel and sound like a regular set, but designed to last 3-5 times longer."
