Sfarzo Touchtones Cryogenic Treated .008-.038

We start by using high-quality core wire and the best U.S.A wrap. The wire is first cryogenically frozen below -320 F, then brought to room temperature.

Cryogenically treated strings are metallurgically enhanced as the process helps to tighten the structure of the alloy resulting in a reduction of surface roughness and an increase in structural durability. They hold their pitch for a clear sound that can be felt and heard.
