The organ in question is the only surviving instrument built by J. Gremse, distinguished from other organs of the same period. This makes it an invaluable cultural monument. Additionally, it incorporates old parts and pipes that are significant in the context of Latgale and are well-integrated into the current instrument. The church, constructed of wood, provides a relatively favorable climate for the organ's preservation.

The organ is located at the western end of the church on a wooden balcony. The organ's prospect, set behind the balcony edge, allows space for movement and maintenance. It features five pipe fields with larger ones on the sides, and the sounding zinc pipes from the Principal 8' stop are painted with aluminum paint. Some elements of the prospect and structure might have been used from the old organ.

The console bears the inscription: J. GREMSE - DUBENA SCHLOTTENHOF - ST. LIEVENHOF. "Dubena" refers to Dignāja in German, "Schlottenhoff" to a place near Dignāja where Gremse's house was located, though the connection to Līvāni is unclear. Likely built shortly before World War I (around 1910-12), the organ incorporates pipes and parts from late 18th-century organs, possibly from nearby Puša. Post-World War II, the organ underwent significant repairs and modifications.

Before restoration by A. Melbārdis in 2010, the console had several disconnected devices, such as couplers, and the original wire supports beneath the windchest were missing. This resulted in the wires pulling out from their slats due to their weight, rendering the organ unplayable as the pneumatic action ceased to function. This organ, the only known J. Gremse instrument in Latvia, is valuable both historically and for its integration of earlier baroque organ pipes and parts.
