The The organ of Gardiner Street church is basically a new instrument, but one which incorporates much of the old pipework of both John White and Telford & Telford found in its predecessor. The console has three manuals and pedals, though in an unusual arrangement only two of the manuals speak - the lowermost manual couples together the other two.

The manual action is mechanical, the pedal-action electro-pneumatic and the stop-action electric. There are six adjustable combination pistons to each division.
