Cleartone strings from the Heavy series are, as the name suggests, designed primarily for harder styles. This is matched by a reinforced construction and improved winding ratios of nickel-plated steel to metal core. The use of these materials gives them natural dynamics and a clear sound presentation. Thanks to the "treated" finish, they not only have a longer life, natural attack and are more resistant to corrosion, but also provide your guitar with up to 36% more volume than other "coated" strings, which Cleartone has had scientifically verified and patented.
