The organ was built in 1931 and has 3 manuals, 25 stops and pneumatic action. It came to Panevezys from the chapel in Konigsberg. There is room for 13 more stops which could be added in the future. Goebel made a new organ console with 38 stops which would fill the Cathedral space. In 2008-2014 the instrument was restored by the Lithuanian organ builder Antanas Šauklys workshop.
