Yesterday I showed you this pipe at Bloomsbury Central Baptist Church, but I wasn’t quite sure what it was. Eric Shepherd (who maintains the organ) has the answer:
The Pedal pipe that you show is the Sub Bass 32. It is called a polyphone pipe, and gives 8 notes of the bottom octave down to E, then the bottom 4 notes play the E. There are wooden chambers, which open with large valves to give the different notes. It was from an organ by Compton. If the pipe were to go down to bottom C, the pipe would have to be enormous.
So now you know!
