Hi Joe.
Somewhere in my archive of music I have a book on Hammond Drawbar settings.I've have a look and see if I can find it.
The old way it was done on the old hammonds
was to go by shapes of the drawbars, because when you used to change things on the 'fly' it was easier to remember shapes than it was to remember actual settings. It is a little more difficult to change drawbars on the KN7000 because you have do with the buttons but it's not impossible.
If you want jazz setting s then you will need to include the percussive drawbars but not all at one time.
Regards
Peter B.
p.s. Tremolo/Vibrato/Delay settings will also make a difference to the overall jazz sound.
