-When Percussion is enabled, one of the harmonic busbar contacts from each key is used to trigger the Percussion amplifier. This removes one drawbar harmonic from the palette available to shape the sound. The stock setup removes the harmonic available at the 9th drawbar. Some players prefer to have the top-most drawbar available at all times, even when Percussion is enabled. This modification to the percussion circuit changes the percussion amplifier's trigger source from the 9th harmonic busbar to some other source, usually the 8th.

The following procedure has worked on a B-3, C-3, and A-100. You will probably want a copy of your organ's schematic and wiring diagram for reference.
__Note__: All references to soldering on drawbars are in reference to the Upper Manual "B" Preset group, which is the 2nd group of nine from the left, when viewed from the console seat.
