Rebuilding an existing pipe organ is often a worthy alternative to buying a new instrument.
- An older, thick "Diapason" can be reconstructed into a rather lovely Gedeckt, Rohrflöte, or Harmonic Flute
Additionally, that muddy, thick Diapason can sometimes be reconstructed into a new Prinzipal-type sounding stop
Thin, scratchy 8' Salicionals can become the most delightful mutations (Nazard 2 2/3', Tierce 1 3/5', etc.)
Pallid 8' Dulcianas can become sprightly 4' Principals
Hollow 8' Melodias can become interesting 4' or 2' Flutes
While these creative and cost-effect treatments can recycle ranks of pipes that some might consider trash, they cannot and should not be considered as the end-all of a totally new tonal scheme. If an organ were to be rebuilt, and a new successful tonal scheme developed, some new pipework is almost always inevitable.
