DRAWBARS & PERCUSSION
Ë Manual Drawbars
Your Hammond SKX has two sets of nine Drawbars, one for each Manual. Drawbars, often called Tonebars, are the
heart and the basis of the renowned Hammond Sound and have been used since the first Hammond Organ Model A
introduced in 1935.
There are approximately 253,000,000 possible sound combinations that can be produced by these Drawbars. Each
Drawbar consists of sine waves of different pitches. The illustration below shows how each Drawbar relates to the
keyboard when middle "C" is pressed.
Each Drawbar is marked with a number followed by a footage mark. For example, the first white Drawbar is marked
"8'". This is pipe organ terminology indicating that the pipe used to produce the lowest note on the keyboard on a pipe
organ is actually eight feet long. The numbers from "1" to "8" on each Drawbar represent degrees of loudness - number
1 being the softest, and number 8 being the loudest.
