Haddonfield Swell Pipes

The Steiner organ at The Lutheran Church of Our Savior, Haddonfield, NJ, had suffered from poor tuning practices prior to our taking over the care of the instrument. In 2014 we rebuilt the organ, including straightening, cutting and fitting flue pipes throughout the organ with new tuning slides.
