Installed in 2006, the Cathedral organ was built by the German firm of Wech Orgelbau in Buchloe, Bavaria. The organ’s tonal design was conceived by Robert Wech, and final voicing was done by Robert Wech and Marcus Zoitl.

The organ has mechanical key action and electric stop action, and comprises 31 stops (37 ranks/1,945 pipes) over two manuals and pedal. Manual compass is 58 notes and the pedal is 30 notes. The hand-made case is solid oak; manual natural keys are made of wood capped in ox bone with ebony sharps. The façade pipes are polished tin and the organ’s wind pressure is 78 mm throughout. The organ is tuned using Kellner temperament.
