The casework in natural oak includes pierced grillework details in Gothic tracery style which were specially designed so as to relate the instrument to its surroundings in the cathedral.

The organ has a foot pedal which enables any stops of 4 foot pitch and above which are drawn to be silenced. This makes contrasts of dynamic possible when no hands are free to change stops in the conventional way.

It also has a transposing device, enabling the instrument to be played at three different pitches, especially useful when working with period instruments which usually play a semitone lower than modern pitch.

The blower is contained within the case, which makes the instrument remarkably compact and fully mobile.
