Adding the 4th, 5th, and 6th Harmonic to the Hammond (B3, C3, RT3, or A100) Percussion allows for much more percussion variation by making 3 more harmonics available in addition to the 2nd and 3rd standard harmonics. With the first 3 drawbars out (the usual setup) there is much more contrast between the drawbar setting and the percussion tones. The sharp percussive bite is now available much lower on the keyboard. To get the full effect of this harmonic addition EliminatingThePercussionVolumeDrop is very desirable since this will restore full volume control to the drawbar settings. Two miniature, four pole switches (one for the percussion on/off and one for the 4th, 5th, 6th harmonic selection) and some stranded hook up wire is all that is needed. The switches are available from Mouser electronics (part No.’s below). Note with this design, the 4th, 5th, and 6th harmonics are not available at the drawbars when the percussion is on. The usual percussion setting is some combination of the first three drawbars so this shouldn't be a problem.
