Center Church was not designed to house a freestanding organ in its very shallow gallery. Previous instruments had been deeply recessed into a steeple chamber. For Charles Fisk, it was imperative that the sound-producing portions of the organ be located within the four walls of the room. In the resulting design the Great, Echo, and Pedal are located in a broad but shallow case against a brick wall in the gallery, with the Choir division on the gallery rail.
Opus 54, dedicated in 1971, contains the first embossed front pipes in a Fisk organ, featuring three-dimensional geometric designs in the metal. Economy dictated the use of a few rebuilt ranks of pipes from the church’s former Austin organ and the deferment of the completion of the Echo division until 1974.
