Ian, great idea, I’m into building stuff. My thought was to purchase a used quality organ.
In the past I bought two Wersi organs for a fraction of the original price. Working in a major piano I had a chance to get the shell of an organ – the amplifier was working but the rest had seen better days. Having two top-of-the-line keyboards built in a piece of furniture with a more than adequate amplifier was a dream, I'm sorry I passed it up.
