The Holtkamp Organ at Grace Lutheran Church of Mobile, was designed by Walter Holtkamp, Jr. in consultation with Warren Hutton. Designed for Grace's sanctuary, it features classic voicing, mechanical key-action, and encasement of the 1784 pipes. The case-work not only enhances the visual appearance, but also serves to focus and project the sound. The case design was inspired by the architecture of the church itself. Facing the instrument, you see the Great Organ in the center and the Pedal Organ on the two sides. The Swell Organ is located in a separate division behind the Great front pipes. It is totally encolsed, but has vertical louvers which can be manipulated by the organist to produce a broad dynamic range.

The console is built in plane-sliced American Walnut with an oil finish and is placed forward from the pipe case to provide for the choir. The two manuals (keyboards) are encased in natural walnut. Natural plum and rosewood replace the usual ivory and ebony keys. Tilting tablets (stop Keys) of cherry above the manuals activate the stops or couple the divisions, so that stops from other divisions can be played from a single manual. A solid state capture system with two memory banks supports the combination pistons used to pre-set registrations of the sound of the organ.

At the floor of the console are the pedals and toe studs which preset stops, and allow the organist to engage the "full organ." The swell shoe which controls the louvers of the Swell Organ is in the center of the area.

The keys are linked through fiberglass rods and aluminum roller bars to the wind chests. This mechanical or "tracker" linkage provides expression through variation in attainable accents. For example, "chiff," the tonal exclamation that precedes the fundamental pitch, can be accentuated by a quick touch or attenuated by a slow touch. This "tracker" action produces the sharacteristic sounds of the beautiful cathedral organs of Europe.
