In 2007, a tonal renovation was completed whose goal was to return all available pipes to their original locations and voicing. This project removed two of the added mixtures, replicated the Gemshorn treble and Great Twelfth (thus permitting the original Grave Mixture to be heard), and re-regulated all stops. The organ is now as it was tonally in 1933, with three exceptions: the Great, Choir and Pedal remain unenclosed; the Swell Vox Humana (now in the Sanctuary organ) holds the Casavant 111 Plein Jeu, revoiced as a two-rank mixture; and the Choir Dulciana is absent. For this project, installation and racking work was executed by Spencer Organ Company, new pipes were made by Thomas Anderson (former head of the Æolian-Skinner pipe shop), voicing was by Daniel Kingman, Trompette renovation by Broome & Co., all managed, contracted and tonally finished by Jonathan Ambrosino. Concurrently, Nelson Barden Associates rebuilt the blower, replacing the original D.C. motor with a vintage 3-phase A.C. model. Finally, some structural repairs were made to parts of the organ whose wall attachments had failed, the swell shutter action was adjusted, and the electro-pneumatic relay received a few modifications.
