First Presbyterian Church, Marietta, GA

First Presbyterian Church of Marietta, GA has been home to an Allen model R350 that has served the church well for over 25 years. The church has returned to Allen Organs to upgrade to a much larger, 4-manual GX-460 model that was installed in December of 2025. The new organ is an 18 channel instrument, spread across five different chambers, including the rear antiphonal. A custom built Ingram Zimbelstern is also installed within the left choir loft area. The console itself is testament to Allen Organ’s ability to offer customized console designs upon customer request. This includes reverse color keys and multiple finishes on the console. Please see the expansive stoplist for this organ, below. On top of the stops listed, each division also has two additional, user defined, changeable Genisys voices that further add to the tonal palette.
