Noel wrote about variations in AGO pedalboards. It's also been a while since I studied the spec, but in adition to = variations, there are discrepancies. Both of these, I suspect, account for = the differences we see. The radius of concavity and radiation allow for a range of 8 to 8-1/2 = feet.=20 For an 8 ft radiation versus 8-1/2 ft, there will be equal spacing between = adjacent pedals, but at no where else along the pedal playing surface. = Speaking point is supposed to be at the halfway depresssed point of the = pedal, but AGO only allowed a total travel of 1/2 inch--far too shallow in = my opinion. The playing surface of the sharps is supposed to be 6-1/2 = inches as measured but 6 inches if you calculate from other supplied = information.=20 In any case, I feel very sorry for any engineer who has to design a = pedalboard for manufacture based on these so-called "specifications". AGO = should really revisit these, and have an engineer or builder lead the team = that does it. It's really very shameful what they have. I learned to play on an electronic with a 25 note flat pedalboard, and had = trouble when I went to an AGO board--the pedals are just too close to my = feet. I find theatre organ pedals are often a bit lower and much more = comfortable for me to play--I'm also tall, but mostly tall in the legs.
