Updated through online information from James R. Stettner. -- Blessed Sacrament Chapel is a side transept chapel. The organ is in an elevated chamber at the rear of the chapel. It is entirely chambered with no visible pipes. The console sits directly beneath the grille front with the organist facing forward; the third manual plays selected stops from the Gallery Organ. The Blessed Sacrament Chapel organ can also be played from the gallery console.
