First Presbyterian Church in Pittsford, New York [Sound] "Very quiet and effective." [Mechanism] "The tremulant copied from memory from the one in the Paul Fritts organ at Notre Dame University. This tremulant gets its wind directly from a valve on the main bifurcation windline, through a 1" copper tube about 6" long. It is almost identical to the one in the organ in Marquand Chapel, Yale University." Pipe organ components Organ stops
