The Johnson Organ Company of Westfield Massachusetts installed its Opus 254 in The Presbyterian Church of Catasauqua in 1868. Three gothic arched flats of open diapason pipes make up the facade of the organ. Across the horizontal top of the casework are carved fleur-de-lis. Constructed of oak, the casework is presently stained a dark walnut color. The entire instrument is located in an alcove at the front left side of the nave.
In 1952, the Muddler - Hunter organ company of Philadelphia electrified the tracker action. New pipes and console were added to the organ in 1972 and 1994.
