Hi Peter
I too love the Hammond sound, and was thrilled when I first found the video and passed it around.

I have a KN7000, and eventhough it has great organ sounds, it just doesn't quite get me back to my B3 days in the 60's and 70's.

I found a way of coming as close to the real thing. Eventhough I am only moderately adept with computers, I decided to venture into the realm of Software synths. With a fast computer and plenty of RAM, this is absolutely an incredible duplication of the B3. I use it at home and playing out. http://www.arbitermt.co.uk/ni/products/b4ii.htm

Just a thought
