Technical Details
It is a 48 keyless concert organ containing 172 pipes—there is no percussion.
The scale, which is virtually fully chromatic (unlike most organs of this size), was devised by David Leach and is only used on his organs. It is divided as follows:-
18 melody, 16 accompaniment, 12 bass.
The registers are controlled by a duplex system. This means that holes which normally control accompaniment pipes, operate registers whilst the changeover/duplex hole is open. This system reduces the width of the card that would be required if each register had its own hole.
There are eight ranks of melody pipes providing a wide range of tonal colours.

Hole 48 controls the accent/forte mechanism. Whilst this hole is open (often as a chain perforation), the violin, gamba, and three rank mixture will be added—producing a sound like a cornet--- irrespective of what registers are already set. This can be used to accent certain notes or play forte on longer passages.
The 12th and 17th will only play on the accent/forte. All other registers can be set independently.
The ornate front was made and decorated by D.B. Jones of Stratford on Avon.
The original owner lived in Leamington Spa and chose Warwick Castle as the main theme for the decoration.
