When Micro-Frets closed operations in Maryland in either 1974 or 1975, the company assets were purchased by David Sturgill. Sturgill, who served as the company president of Grammer Guitars for three years, let his sons John and Danny gain access to leftover Micro-Frets parts. In addition to those parts, they had also purchased the remains of New Jersey's Harptone guitar company. The two assembled a number of solid body guitars which were then sold under the Diamond-S trademark. Unfortunately, that business venture did not catch on, and dissipated sometime in 1976.
Instruments previously built in Independence, VA during the 1970s.
