The main organ was ordered in 1763 from the organ builder Victor Ferdinand Bosshard (1699–1772) from Baar.
 It was delivered on 24 April 1772 by his son Karl Josef Maria Bosshard (1736–1795), as his father had died that year.
 The choir organ was also ordered from Ferdinand Viktor Bosshard and was delivered on 29 September 1772.
 The original casing of the main and the choir organ are still preserved.
 However, the organ case in the south transept is a mute.

The main organ was rebuilt in 1942 by Kuhn Organ Builders from the year 1942.
 In 1975 the organ was rebuilt again, the visible pipes were retained, but the majority of the inner workings were replaced.
