[4] The next year, Martin made one for Jackie "Kid" Moore, a "12-year-old singing cowboy from Milwaukee, Wisconsin.

One of those craftsmen was Mike Longworth, a banjo player from Tennessee, who Martin hired specifically to bring the D-45 back.

The new D-45, released in 1968, cost $1,200 and was the most expensive flat-top steel-string guitar made in the United States at the time.

By 1969, Martin sold twice as many D-45s as during the entire 1933–1942 run; customers included David Crosby and Jimi Hendrix.
