• The organ in the Cathedral in Graz was built by Klais in 1978. The instrument has four manuals and an independent pedal. Large parts of the old organ case with decoration were used during construction. This was made by Veit Königer in the eighteenth century. The new organ case was designed by Jörg Mayr. The Trumpet work is placed on an electric windchest and can be used from any manual. It was added to the organ in 1998 by Klais during a renovation. A setzer installation was also added, and the Spielflöte 8' of the pedal was converted into a Gedecktbaß 8'.
  
• The organ was rebuilt by Rieger Orgelbau in 2022-2023. They built a new organ in the existing case, using a large part of the pipework. The renewed instrument was dedicated on November 26, 2023. Christian Iwan played the inauguration concert.
