TouchTone Cryogenically Treated Acoustic Guitar Strings Medium 13-56

TouchTone Acoustic guitar strings, made in the U.S.A by Sfarzo String Company Sfarzo starts by using high quality core wire and the best U.S.A wrap. The wire is first cryogenically frozen below -320 degrees 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.   The result is a reduction of surface roughness and an increase in structural durability   Cryogenic strings were introduced in the 1980's. Sfarzo Strings improved the process and taken the strings to another level.
