This instrument was custom made for Hub Hildenbrand by Mukunda Biswas, a luthier in Calcutta (India). Hildenbrand made a sketch for him and they discussed the details. "He did a really amazing job! I am very grateful for his dedication and inspiration." The Duitarod combines a 6-string acoustic guitar neck and a sarod based 4-string fretless neck. In addition, it has 12 resonance strings and two cikari-strings, which are played as a drone and rhythmically. "My idea for this instrument was to expand the expressive range of the guitar."

The name is composed of "Dui" (for "two" in Bengali, that is, double neck guitar), "(G)uitar" and "(S)arod".
