The stoplist present in the June 1926 issue of THE DIAPASON (see DOCUMENTS) seems to omit the Echo stoplist and uses the ECHO name with the Pedal stoplist; the Echo division was installed, though.

From the church's Facebook: The original organ, given in memory of David Willis Beaty, was built by the Austin Organ Company of Hartford, Connecticut, based on specifications by and under the supervision of John A. Bell, organist of the First Presbyterian Church of Pittsburgh. It had four manuals (keyboards). In 1969 -1970 the organ was rebuilt by the Kennedy Organ Co. of Bethel Park, PA. A new three-manual Austin console was installed, actions were replaces in the four major Divisions of the organ and other repairs were done. Fourteen ranks of pipes were replaced. Total cost of the work was $43,289.

In 2001- 2002 the organ was again rebuilt, this time by the Fischer Organ Co. of Erie. Each of the more than 2,350 pipes was removed, sent to Erie, cleaned and re-voiced. The chests and actions were re-leathered and the organ was rewired. In the Echo Division, pipes were replaced by electronic voices and some electronic enhancement was added to the Pedal Division. The organ console was completely refinished, with much of the woodworking done by church member Ron Russ.

The most significant change in this organ update was the addition of Antiphonal Division in the rear balcony. Very unique among pipe organs, the Antiphonal Division includes nine ranks of pipes (561 total), which are played from the existing console. Most exciting of this update was the Trumpet-en-Chamade. When completed the organ a total of 2,967 pipes and 10 electric voices. Total Cost of the 2001 - 2002 renovation was approximately $254,000.
