Concerning pipes and sound in Nuts and bolts Posted June 25, 2020 12 hours ago, Colin Pykett said: OK Stanley, since you asked so nicely, and because it's far too hot to think of going outside, here goes (with apologies to John if he thinks I'm paddling in his pond) ... Absolutely no apologies needed! I found your explanations both interesting and enlightening and I agree with them entirely. I might add that I respect and enjoy the benefit of your far greater knowledge of the subject. I have heard for myself that organs with relatively low wind pressure can be at least as 'loud' as the high-pressure ones which held sway in this country in the early 20th century. There are far more important factors in play: location within the building, the building itself, the use of strong mixtures, etc, etc. My personal preference has always been for a brighter sound, especially since my hearing has begun to deteriorate!
