Part of my current pipe organ obsession. Found this amusing. In Guinness as the the "Loudest Musical Instrument Ever Constructed"
A quote from the page :
The Guinness Book also recognizes the Grand Ophicleide 16′ in the Pedal Right division to be the loudest organ stop in the world.
The Grand Ophicleide produces 130 dB at 1 metre distance
Check out the picture of the console. Largest in the world. Captain Kirk would be envious.
