Do let me know when they're happening, please.
This subject remains close to my heart. My organbuilding career started at GD&B in the late seventies and scarcely a month went by without a trip to New College. Besides tuning, we replaced the non-return valves on the pedal soundboard: they allowed the 16' reed to extend down to 32' via grooves in the upperboard.
Nowadays we might think twice about doing pedal extensions this way - I remember us having to remove half the pedal organ just to access the valves under the top upperboard veneer - but it was at least a valiant attempt at a very new trick.
Many things at New College were experiments. Some worked and some fell hideously flat. But more importantly, many still provoke discussion. To say that wasn't a good thing would be boring indeed.
