The inscription on the north wall inside the organ casing reads, "Diese Orgel hat erbaut im Jahre 1838 der Orgelbauer und Mehanicus John Buchert" ("This organ was built in 1838 by the organ builder and mechanic John Buchert"). The casing and the prospect are the only parts of the Drustu instrument that remain from Buchert’s original construction. The significance of John Buchert is underscored by the fact that the notable and prolific Liepāja organ builder Kārlis Hermanis began his apprenticeship with him.

The current organ was dedicated on December 6, 1901, built by the Riga organ builder Emīls Martins. Funds for the organ's construction were collected twice. The initial fundraising effort initiated by the nobility in 1898 did not yield the expected results and was instead used for exterior repairs of the church. When the nobleman von Sievers proposed using the remaining funds to repair the existing organ, the congregation disagreed and started a new donation drive, which quickly gathered more than enough funds, primarily contributed by local farmers. Notably, a piano craftsman named Kārkliņš from Moscow donated 100 rubles. The total cost of the organ, including transportation and installation, was 1613.97 rubles.

This organ features one of the two known surviving prospects built by John Buchert. The instrument itself, built by Emīls Martins, is a pneumatic action organ typical of the period, with metal pipes manufactured by the Aug. Laukhuff factory.
