Getting the voicing right on a Makin Organ

Spending time to get the voicing right with an organ is critical in the eyes of Dr Underwood from East Leake near Loughborough:- 

It was a pleasure to meet you yesterday and completely fascinating to watch you go through the process of voicing my Makin Organ with Ian Tracey. I was truly amazed at what you were both able to achieve in carrying out the process. I’ve enjoyed exploring the organ’s new sounds; the instrument now sounds very fine indeed. Thank you so much for all your help with the entire project: much appreciated.
