Here's the Grand Diapason 8' for the Grand division of the renovated IV/104 Leeds Town Hall organ on the voicing machine at Nicholson and Co. The new organ is due to be completed early in 2024.
The pipes were made by us, using original Abbott & Smith tools that were probably used to make much of the fluework of the previous organ.
The pipes, on 7" wind, have been voiced by Nicholson's head voicer James Atherton with wide but low diameter cut-ups, minimal nicking, and slots that are 1/3rd diameter wide and 1/3rd diameter from the top.
Nicholson's says: 'These combine to give a fresh and incisive quality, with a harmonic brightness not usually found in large diapasons such as this one. We can't wait to hear it in the hall!'
