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.
Cryogenic strings were introduced in the 1980's. We at Sfarzo Strings improved the process and taken the strings to another level. Our users tell us so too !
"I been playing guitar for 53 years. I recently switched to Touchtone strings for my 1971 Martin d-18 and my 1968 Yamaha fg-75 my band immediately noticed the difference and the bass player commented the first time I strummed the Martin with the Touchtones "Wow, your guitar sounds really rich and has great tone today". I told him I was trying new strings and by the end of our rehearsal I knew it was going to be Touchtones forever! I want to thank you so much for creating such an amazing product! - Sandy Poze guitarist for Front Porch Swing and Rhythm Method
