 Although several of the 1985 tonal additions have been retained, the tonal basis of the present instrument is formed by the Norman & Beard pipework of 1900.In the 2010 rebuild all of the chorus reeds were re-voiced with a brighter tone so as to integrate with the original work.Three new replacement Mixtures and a Tuba were added to the specification and the number of stops was reduced from 66 stops down to 44, exactly the same number as in 1900.
