Black Diamond Strings Sold to Guitar String Manufacturing

The ownership of Black Diamond Strings has transferred to Guitar String Manufacturing (GSM) located in Santa Rosa, CA.

GSM have arranged to procure the exact winding machines and wrap formulas Jim Cavanaugh and his family have crafted. The comapny says its goal is to continue to provide customers with the same products they have come to expect from the Black Diamond brand.

With the sale, the manufacturing of Black Diamond Strings is now moving from Florida to California. The company says production of strings in the new location will start back up on Nov. 20, 2018.

"After conducting an extensive search to find the right company to take over Black Diamond Strings and its customers, we certainly feel we have found that with Greg Sfarzo and Guitar String Manufacturing. Greg and his team are up and running and ready to take orders. Join us in wishing Greg the utmost success with this historic guitar string company. And as always, feel free to continue contacting Super-Sensitive Musical String Co. for orchestral accessories and of course National brand guitar picks," says Jim Cavanagh of Super Sensitive Musical String Company.
