INTRODUCTION
The Johannus WM-44 LDS organ is custom built for The Church of Jesus Christ of Latter-day
Saints. It has been designed primarily as an instrument for accompanying congregational
singing as well as to provide a variety of tonal color for prelude music.
Recordings of fine pipe organs from around the world are used to create the beautiful
sound of this Johannus organ. When a player presses a key, we hear the actual recording of
a pipe, not just an imitation of one.
We hope you enjoy using this instrument as much as we enjoy building it. Should you have
any comments or questions, please contact your authorized Johannus dealer.
