St Edmundsbury Cathedral Organ was built by Nicholson and Company in 1970. It is sited in a specially constructed chamber in the northeast corner of the building, speaking directly into the North Transept and the Quire. Most of the pipework and some of the soundboards from the old Norman and Beard instrument were incorporated into the new instrument, although notable new pipework included the Positif Organ, most of the Pedal Organ, and the Trompeta Real. The instrument is uncased.

The long anticipated work to refurbish the organ is taking place during 2010.
On Sunday 10 January at 5.00 p.m. the organ was heard for the last time with a rendition of Olivier Messiaen's great cycle of music celebrating the birth of Christ: La Nativité du Seigneur. With scaffolding in place from early January, the entire organ will be removed. Some of it will be driven to the factory of the renowned organ builders Harrison and Harrison on the outskirts of Durham for refurbishment. Quite a lot will be disposed of. Later in the year the new components will arrive in Bury St Edmunds and Harrisons will gradually construct the instrument in the chamber. New blowers, wind systems and reservoirs, soundboards and actions will arrive, followed by the pipes. Finally two huge cases will arrive, the crowning glory of the instrument: visually the organ has been incomplete for forty years. They will be constructed and decorated in the Cathedral before being hoisted into place. For a short period, scaffolding will need to be put up in the Quire to facilitate this. There will follow in the late autumn a period when the organ is 'voiced' - each pipe (and there will be over 3,500 of them ranging in length from 32 feet to a fraction of an inch) will be adjusted to speak to its greatest advantage. The end result will be quite spectacular!
