The corporate offices and production facility of Super-Sensitive Musical String Co. and Black Diamond Strings had a surprise visit in March from Adam Blackstone, a bass player and company endorser. Blackstone was in town working with Tim McGraw and Faith Hill on their upcoming tour, and he wanted to visit with the company’s President, Jim Cavanaugh. In addition, he enjoyed a tour of where his bass strings are made. Most recently, Blackstone is known for his work with Justin Timberlake.
