Micro-Frets was a short-lived brand that operated out of Maryland in the late 1960s and early '70s. The firm produced an estimated 3000 total instruments before closing its doors in 1975. On the vintage market, Micro-Frets are known for their oddball shapes and design features, as well as the vibrant finishes that set them apart from anything else produced in this era. The brand name has been revived since the original closure, though Micro-Frets fans are mostly interested in vintage examples.
