A reed stop of 32', 16' or 8' pitch, usually found on the pedal. Adlung, Grove and Wedgwood list it as synonymous with Bombarde, but Audsley says: �The Bombardon has been confounded with the Bombarde, but they are properly two distinct stops tonally. The voice of the Bombardon should be between the voiced of the Bombarde and the Bassoon, while partaking of the character of both.� Grove also describes it as a �mild-toned English Bombarde of c1850�. The stop is named after the orchestral instrument of the same name, which it is supposed to imitate. The Italian word Bombardone means "great Bombarde".
Osiris lists eight examples of Bombardon at 32' pitch, five at 16', and one at 8'. Only one example of Bombardone is known.
