Pulling the brown drawbars makes the tone deeper and fuller. The second brown drawbar is the “sub-octave” of the third harmonic. The first brown Drawbar is the sub-octave of the fundamental Drawbar. The brown drawbars are the two ones to the left, and these produce harmonics below the fundamental tone. The other white Drawbars are octave intervals of the fundamental tone of increasingly higher pitched notes. The fundamental, ‘core’ tone is created by the first white drawbar. There are three different colors on the drawbars, brown, white and black.

On a console, you will have 5 groups of drawbars, two for the lower manual and two for the upper manual, each of which consist of 9 drawbars, and one for the bass, which has two drawbars. When the drawbar is pushed in all the way, no sound from this drawbar is used in the final sound. This terminology is borrowed from pipe organ technology, where this number actually describes the length of the pipe that is used to get a certain tone.Įvery drawbar has 8 settings, which indicate how much of a particular drawbar’s tone is added to the final signal, with 1 being the softest, and 8 being the loudest. As an example, the first (brown) drawbar is marked 16′. They are also sometimes called tonebars, and they are used to shape the sound.Įach drawbar is marked with a number in feet. The drawbars on a console Hammond or the clonewheels can be a source of much confusion. Whereas the preset sounds seem to be more targeted towards the emulation of pipe organ sounds and have as such limited usage in the typical blues / rock Hammond vocabulary, some of them are quite usable, Here’s an example using the ‘Ab’ (‘Tibia Clausa’) on the lower manual: Overview of the factory presets on a Hammond console (B-3, C-3, A-100) Lower Manual Overview of the factory presets on a Hammond console (B-3, C-3, A-100) Upper Manual Hammond Console Presets Lower Manual Preset Key Iâ€™m learning to be a leading-edge designer of trailing-edge technology.Hammond Console Presets Upper Manual Preset Key When I do that, I will start a thread on ARF about the restoration process. I hope to start restoration on it within the next couple of months. Unfortunately all of its capacitors are of the wax-paper variety.

Their uF is still in-spec and they donâ€™t have DC leakage. TONE GENERATOR Table of Contents Voice List Drum Voice List Drum Voice Name. Fortunately most of the Mylar tubular capacitors Iâ€™ve seen are still good. It was during the 1965-1970 time period when Mylar-dielectric capacitors came on the scene. It is possible that someâ€later productionâ€ Hammond organs were manufactured with Mylar polyester-dielectric tubular capacitors. This can give the organ a â€œdull lifeless tone quality.â€ Replacing each capacitor in the tone generator with the precise uF value marked on the old capacitor will restore brightness and balance to each note.Īlthough the organ will still be â€œplayableâ€ with 100 out-of-spec wax-paper capacitors in the tone generator, it wonâ€™t sound quite right.Īs for the tubular capacitors in the amplifiers, it is a good idea to replace them also, for the same reasons that we recap our vintage radios. Unfortunately, paper-dielectric capacitors tend to increase in uF as they age. These are often wax covered tubular paper-dielectric capacitors. The capacitor uF values were carefully chosen at the Hammond factory to â€œvoiceâ€ the organ. Each capacitor forms a parallel tuned circuit with its associated pickup coil. Hammond restoration experts have explained that each and every pickup coil in the tone generator has a â€œtuningâ€ capacitor in parallel with it. Hereâ€™s what Iâ€™ve been able to learn about recapping vintage Hammond tone-wheel organs:
