D-28

Johnny Cash

Martin D-28 (1961, later painted black) — Cash's primary Martin from 1961 to 1982, when he spray-painted it black to match his "Man in Black" persona; the guitar he famously played at his 1968 Folsom Prison concert

Waylon Jennings

Martin D-28 (1946) — Jennings' primary songwriting guitar at home and on the road for decades; one of the first D-28s built after WWII, blending pre-war herringbone styling with post-war construction. Preserved today in the Martin Guitar Museum
