Leslie 3300 Owner’s Manual
ADVANCED OPERATION
Controlling the Overdrive depth of the Leslie
3300 from an Organ. For this example we used
an XK-3.
1. Set the MASTER VOLUME control on the XK-3 to the middle or center
position and fully depress the Expression Pedal if one is connected.
2. Set the TUBE MODE control of the Leslie to the middle position and turn
the TUBE DRIVE LEVEL control fully counterclockwise (TUBE OFF).
3. Set the VOLUME control on the Leslie at the position where you get your
desired maximum volume without distortion.
4. While playing the organ, thrn the TUBE DRIVE LEVEL control on the
Leslie clockwise and set it at a point just before the distortion begins.
5. Set the MASTER VOLUME control on the XK-3 to the maximum posi-
tion. Play the organ and make sure you here some distortion. The Distor-
tion will increase as you turn the TUBE MODE control on the Leslie clock-
wise.
6. While playing the organ you will discover that the depth of the Overdrive
will change depending upon the position of the Expression Pedal.
You can achieve similar effects on other organ and keyboard prod-
ucts.
Try changing the location of the MASTER VOLUME control
(step 1) on the XK-3 to find your favorite effect.
NOTE: Be careful not to have extremely deep overdrive. Depending on
the position of the Expression Pedal, you may not be able to
control the overdrive depth, and the organ sounds may always
be distorted.
How to effectively use the MIDDLE and
TREBLE controls on the Leslie 3300
The frequency characteristics of the Horn Rotor are very similar
to those Found on other traditional Leslie like the model 122.
If you desire, you can flatten the frequency characteristics by set-
ting the Middle control slightly less than the center position and
the Treble control slightly more than the center position.
Factory set positions for the Trimmer Controls
NOTE: The position of the Trimmer control may vary slightly from prod-
uct to product.
The Trimmers are used to finely adjust the slow or fast speed of
horn and drum and to set the rise and fall times to your personal
liking. There is no “correct” speed, but the factory settings repre-
sent the setting that most players will like best. The trimmers have
to be used with the correct size screwdriver and must be set with
care. Once the trimmers are set to your personal liking it will not
be necessary to adjust the trimmers all the time. It is always pos-
sible to return to the factory settings (see next page)
