Sfarzo Alloy 5109 Acoustic Guitar Strings

Alloy5109 strings are treated with an environmentally safe polymer liquid that evaporates quickly. REDF.R.E.D, (a Sfarzo Brand) polymer coating creates a resistance between the string wrap and core against acidic perspiration. Our polymer coating lubricates and protects against premature corrosion, slowing down the corrosive process while still retaining excellent tone.
