How an unsuccessful 1959 acoustic guitar became a symbol of Kurt Cobain.
In the late 1950s, the American company Martin released an unusual model, the D-18E—an acoustic guitar equipped with two electromagnetic pickups. The company attempted to keep pace with the coming electrical era in music but failed: only 302 units were produced over two years before the model was discontinued.
