In 1694 the new building was carried out by Grotian. Technically, optically and tonally, Grotian leaned heavily on the organ builder Joachim Kayser . Both were able to maintain their independence in East Friesland despite the pressure of competition from Arp Schnitger. In 1772 the organ was renovated by Dirk Lohman ( Emden ). The beautiful inscription behind the music stand dates from this time: Eedo Siewerts / Organist en Schoolmeester . The repair by HF Thielke (Emden) meant that the condition of the instrument tended to deteriorate, as the organ builder Arnold Rohlfs explained in a letter of complaint to the consistory in 1843. Gerd Sieben Janssen ( Aurich ) rebuilt the organ in 1854, replaced two registers in the upper section and the keyboards and expanded the missing bass notes. In 1892 Johann Diepenbrock ( north ) repaired the organ. The original trumpet was replaced in 1930 by Max Maucher (Emden). Jürgen Ahrend restored the condition from 1694 in 1991. The pipes in the prospectus were covered with tin foil, the original oak case was freed from the later white color and the keyboards with a short octave and the wedge bellows were reconstructed. In addition, a modified mean-tone temperature was applied. The wind chest is original.
Overall, the organ has a multitude of colored sounds that differ in some respects from Schnitger's sound concept. Grotian built more traditionally, while Schnitger, for his part, was considered progressive. Grotian's pipes have a higher lead content and are less finely crafted than Schnitger's. In the upper section there is an independent flute choir in addition to the principal choir. Sesquialtera and trumpet are distinguished by their own sound character. While the Quintadena has a narrow scale , the Holzgedackt has a wide scale . Visually, the rich carving and the side blind wings, which contain silent pipes, are eye-catching.
