DRAWBARS
1. TONE CONTROL

the vintage Hammond B-3. It gently cuts the treble.
e setting range is -9 to +9, and it becomes neutral when set at “0”.
“-1” corresponds to the maximum of the B-3/C-3 tone control, “-5”, the middle,
“-9” the minimum.  e tone control found on the B-3/C-3, it’s value can not be set
at “+”, but on this model it’s possible to boost treble to some extent.

ting range is -9 to +9. It gets neutral at 0.
4. FREQUENCY - MIDDLE

THE EFFECTIVE USE OF THE MIDDLE FREQUENCY
The frequency response of the horn rotor in the
Leslie speaker is not  at. It has a peak from 1kHz
to 3kHz that it is another component of the classic
HAMMOND sound.
When you use this organ on line out without a Le-
slie speaker, you can get the similar e ect by set-
ting the FREQUENCY - MIDDLE to about 2kHz, and
the GAIN - MIDDLE to “+”.
PRESET PARAMETERS
Equalizer is a Preset Parameter, designed to ac-
tively use as one of the tone-making parameters.
However, it is not practical to use Equalizer as a
tonal complementary tool to match the location.
In such a case, if you switch OFF the P. LOAD RV/EQ
in the PRESET function mode, the Equalizer value
does not change when the preset is recalled. (P. 60)
