OVERDRIVE
OD9Pro+

OD9Pro+Overdrive
●An evolved version of the OD9. In BOOST mode, newly added mode switch
(BOOST/NORMAL) provides smooth and pure tube sound by reducing high and low
ranges and boosting mid-range. In NORMAL mode, OD9Pro+ enhances the OD9’s fat
and natural scream sound.
●OD9Pro+ uses a stabilized DC-DC voltage converter to bump 9 volts (plus and
minus 4.5 volts) up to 18 volts (plus and minus 9 volts). Operating voltage is
switchable via an internal DIP switch accessible through the unit’s battery compart-
qIN (input jack)
Input jack to connect to the output of guitar,
other effects or related equipment. The
product automatically turns on when a plug
is inserted into this jack. When not in use,
disconnect plug from input jack to preserve
battery life.
* When an external AC adaptor supplies DC
power to this product, the power is always
on and battery is preserved regardless of
input jack connection.
wOUT (output jack)
Output jack to connect to input of amplifier
or other effects.
eDRIVE
This controls overdrive level. Turn it clock-
wise for more overdrive and counter-clock-
wise for smooth natural clean sound.
rTONE
This controls the amount of high frequen-
cies. Turn it clockwise for more treble and
counter-clockwise for less treble.
18V↔9V

tLEVEL
This controls output level of effected
signal. Typically output levels of both
normal signal and effected signal
should be adjusted to equal levels.
yBOOST/NORMAL
Switch for BOOST/NORMAL. In BOOST
mode, it provides tube sound in which
mid-range is boosted by 3 dB.
In NORMAL mode, classical tube sound
is available.
uFOOTSWITCH
Switch for bypass/effect. Stepping on this
switch alternately turns effects on and off.
* Effect turns on when you depress the
switch and effect turns off when you
depress and release the switch.
iLED INDICATOR
This indicates the bypass/effect status
and battery condition. It lights when plug
is inserted to input jack and effect is on.
No LED light indicates the battery is low
or not installed. In this case replace
the battery.
oDC IN (power input jack)
Jack for connection of external
power supply to effect. Be sure to
use the correct Maxon AC adaptor .
For further information on AC adaptor,
refer to page 26.
* Turn down amplifier’s volume
 to the minimum before con-
necting AC adaptor or DC plug.
!0OPERATING VOLTAGE SWITCH
Slide it to left side for 18V (±9V)
and right side for 9V (±4.5V).
* Turn down amplifier’s volume to the
minimum before sliding this switch.
!1INTERNAL LED INDICATOR
This indicates the status of operat-
ing voltage. It lights at 9V (±4.5V).
No LED light indicates the operat-
ing voltage is 18V (±9V).
ment. OD9Pro+ can also be used at 9 volts (plus and minus 4.5 volts). Stable
sound is constantly available regardless of selected voltage.
●Tr ue Bypass Switching using 4PDT switch lets your instrument’s signal pass
through a non-electronic bypass line when the effect is disengaged, feeding your
amp with direct, unaltered signal from your instrument.
●Easy-access, no tools battery compartment.
