WHAT ARE “CUSTOM TONE WHEELS?”
When the tone-wheel Hammonds - B-models,
C-models, A-100, etc. - were being manufactured,
each individual organ was subjected to a rigorous
series of checks and tests to insure the quality
of each unit, and to insure that all the units
representing a particular model series all sounded
alike. However, since the very newest B-3-type
organ is at least 45 years old, vintage organs are
dependent for their sound on analog components.
Several factors may aff ect the sound of a particular
unit. Thus, a B-3 manufactured in 1959 may well
have a slightly different tone than one made
in 1969, not necessarily because of the year but
because of slight diff erences in component values
among other factors. Also, many characteristics
of the Hammond Organ, especially as heard in
much jazz and rock music, have to do with the
overall condition of the instrument. The Custom
Tone Wheel feature is included to allow you to fi nd,
or create the nearest approximation of what you
want your “Hammond Sound” to be.
All of the Parameters described on this page and
on the following pages comprise a Custom Tone
Wheel. These Parameters cannot be Recorded as
individual Patch Parameters; however, a Custom
Tone Wheel can be Recorded as part of an ORGAN
Patch.
FOLD BACK
On the earliest model Hammond Organs, the
Sub-Fundamental Drawbar (the one marked,
“16’”) would continue to play all the way down to
the lowest “C” (“1C”). Newer models such as the
Hammond Models X-66, X-77 and Concorde do
the same, however, the 8th harmonic Drawbar (the
one marked “1’”) continues to play up the keyboard
to the next to highest “C” (“5C”) on the Keyboard.
On a vintage B-3, C-3, A-100, etc., the lowest note
produced by the Sub-Fundamental Drawbar is the
2nd “C” (“2C”) from the left end of the Keyboard,
while the highest note that can be played by the
8th harmonic Drawbar is the 4th “F#” from the left
end of the Keyboard. The lower and higher keys on
the keyboard
Fold Back
, in that they repeat the
pitches played by other notes.
