The first organ in the Cathedral was built nearly 200 years after construction was completed. The first great organ was built in 1726–30. The town council voted to have the organ built on 5 June 1726. They hired Gottlieb Leuw from Bremgarten in September 1726. By January 1730 his work was nearly finished and the town began searching for an organist. While the main organ was finished in 1730, the ornamentation and finish work continued until 1736. This first organ had 38 organ stops, with a breast and back work as well as an echo work with pedals.
