Kiedrich, Valmentishaus (2026)

The Van Vulpen organ in De Hoeksteen in Zwijndrecht was sold by us to the chapel at the St. Valentinushaus in Kiedrich on the Rhine. The client desired various modifications and additions:

1. The bellow was releathered.
2. The interior of the organ was cleaned and the mold deposits removed.
3. The Quint 2 2/3' was expanded with a Tierce 1 3/5' in the treble.
4. The transmission of the Subbass 16' and the Holpijp 8' was removed and 12 new pipes (in oak) were added.
5. The Subbass 16' was originally positioned against the rear wall of the organ case. To tune the organ, these pipes had to be removed first. The Subbass pipes are now housed in an oak case and on a new windchest for the Subbass 16' and an Open 8' (the consultant involved, Dr. Markus Frank Hollingshaus, had an Octave Bass 8' available from a recently restored organ).
6. The key and register action of the pedal was modified and expanded, and a passage was created between the main case and the pedal. The organ is now easily accessible for maintenance and tuning.
7. A new bellow with regulation was made for the pedal, because the original wind supply had already proven insufficient in Zwijndrecht when using the lowest notes of the Subbass.
8. The entire organ was placed on a raised platform.
9. The organ in Kiedrich was recently installed and completed. Subsequently, the instrument was inspected by organ consultant Dr. Markus Frank Hollingshaus.
