A huge cabinet with a rotating speaker on slide contacts, motors, gears. We don't have one and we wouldn't know where to put it anyway. The amp under the organ is only 20W AFAIK with a huge speaker. That's real watts, not PMPS or whatever kids call "power" these days. Meaning it can make the sound of a large pipe organ and not lose steam after holding the bass chord for more than a hundred milliseconds. > > Sure, but can you flip a switch and be playing the flute or er-hu? > Actually you could. Ours doesn't have the flute presets but drawbars. With these you can set the ratio of all the harmonics and the manual shows the settings for a lot of common instruments. Some sound real, some don't. But we also have a small environmentally friendly (zero electric power, made from wood) flute. Not that I can play it but my wife can. Regards, Joerg http://www.analogconsultants.com

When you take it apart you end up with hundreds of pieces. It is the most complicated concoction of moving mechanical parts I ever encountered. The photo at near bottom show just a small part of it: http://www.myplanet.net/x77dude/photos.html Regards, Joerg http://www.analogconsultants.com
