In 1962, Gibson collaborated with the Everly Brothers to produce the Everly Brothers Flattop. This flat top guitar featured a thin J-185-style body and an adjustable bridge. The guitar was unusual in that it featured star-shaped inlays on the rosewoodfretboard, and it had a large double tortoise grain pickguard, which covered most of the top of the body. As the pickguard covered most of the top of the guitar, it limited the vibration of the top, thus limiting the sound of the guitar. The standard finish on the guitar was black, though a few models were natural or sunburst finish. The Everly Brothers Flattop was discontinued in 1972, but was reissued as the Gibson J-180 in the mid-1980s.
