J.W. Walker & Sons, Ltd., Organ Makers, Suffolk, England (est. 1828).
Originally built 1992. Rebuilt with revisions 1995.
20 stops, 22 ranks, 1,777 pipes, 17,000 lbs. total weight.
The space in which the instrument is currently housed (Nordhoff Hall 107) has "tunable" acoustics by virtue of draperies that may be opened and closed in front of concrete walls. The room also is used as a large ensemble and opera rehearsal room.
