Cleartone String's patented treatment is the answer to a decades-old dilemma. Applied at a mere 0.5 micron thickness, our treatment will never flake or fray no matter how hard you strum. Your strings will last longer, so you can keep playing and, as an added benefit, our coating has been proven under laboratory conditions to increase your guitar's volume and sustain up to 36% and 48% respectively. Experience the Cleartone difference.
