OD9 Overdrive
FEATURES AND CONTROLS
●Identical to the original circuit and featuring the JRC4558 IC chip, the OD9
produces natural overdrive of a tube amp that smoothly responds to input
signal level (playing dynamics).
●Easy-access, no tools battery compartment.
●AC jack to connect optional AC adaptor for long hours of continuous use.
①IN (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.
②OUT (output jack)
Output jack to connect to input of
amplifier or other effects.
③DRIVE
This controls overdrive level. Turn it
clockwise for more overdrive.

④TONE
This controls the amount of high
frequencies. Turn it clockwise for
more treble and counterclockwise for
less treble.
⑤LEVEL
This controls output level of effected
signal. Typically output levels of both
normal signal and effected signal
should be adjusted to equal levels.
⑥FOOTSWITCH
Switch for effect on/off. 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.
⑦LED INDICATOR
This indicates the effect/bypass
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.
⑧DC IN (power input jack)
A jack for connection of external
power supply to effect. Be sure to
use the correct Maxon AC adaptor.
Turn down amplifier's volume to
the minimum before connecting
AC adaptor to the product in order
not to damage other connected
equipment.

ENGLISH
OD9
●True Bypass Switching 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.
Low noise mechanical switch is used for effect/normal switching.
●LED to indicate effect/bypass and battery condition for trouble-free
performance.

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-

⑤LEVEL
This controls output level of effected
signal. Typically output levels of both
normal signal and effected signal
should be adjusted to equal levels.
⑥BOOST/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.
⑦FOOTSWITCH
Switch for effect/bypass. 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.
⑧LED INDICATOR

Jack for connection of external
power supply to effect. Be sure to
use the correct Maxon AC adaptor.

CP9Pro+Compressor/Limiter
FEATURES AND CONTROLS
●CP9Pro+ by use of high-quality VCA (voltage controlled amplifier) and RMS
(root-mean-square) sensor, provides natural attack response with low noise.
●CP9Pro+ uses a DC to DC voltage converter to bump 9V up to 18V. PT9Pro+
provides wide dynamic range and sufficient head room against distortion.
●Compression/Limit level response to picking dynamics is easily viewable with
Threshold LED.
①IN (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.
②OUT (output jack)
Output jack to connect to the input of
amplifier or other effects.
③THRESHOLD (threshold level control knob)
Controls threshold level of compression.
(Fig. 1) When an input signal is above the
THRESHOLD level, compression will be
carried out in the manner defined by the
setting of the RATIO control. (Fig. 2)
Compression starts from a low level when
this control is turned clockwise. So turn the
output level up by the GAIN control since the
output level becomes also low. (Fig. 3)
④RATIO (ratio control knob)
Controls compression ratio. Turn RATIO
control knob clockwise to increase


compression from 1:1 (no compression)
up to ∞: 1 (no increase in output level,
regardless of input level increases
above threshold). When the RATIO is
∞: 1, it can be used as a limiter. When
the RATIO is1:1, it can be used as a
clean booster.
⑤GAIN (gain control knob)
Controls output level. When strong
compression is set by THRESHOLD and
RATIO, output level goes down. (Fig. 3)
Turn GAIN control knob clockwise to
have the same volume as Bypass
functions. Output level can be
boosted up to +30dB so that when the
RATIO is1:1, it can be used as a clean
booster.
⑥REDUCTION LED (reduction indicator)
The LED lights when output level is
compressed more than +3dB vs. input
level.

No.4 Slap Bass
Setting to compress slap phrase which
has a lot of peak levels. Attack level
balances with other level with much
