LEVEL knob
This adjusts the volume of the eect sound.
* When this knob is turned counterclockwise, no sound will be heard.
7 The BOSS CS-3 is a compression sustainer that produces long sustain without distorting the original sounds.
7 The attack volume adjusts picking forth widely and provides any drive-sound.
7 As having the tone control function, the CS-3 allows wider variation of sound creation.
7 More-over, featuring the wide range of maximum input level and compression, the CS-3 can be used as an ordinary limiter by turning down the sustain volume.
OUTPUT jack
The output jack is used to connect the unit to
ampliers or other devices.
Guitar Amplier
DC IN jack
Accepts connection of an AC Adaptor (PSA series; sold separately). By using an AC Adaptor, you can play
without being concerned about how much battery power you have left.
* We recommend that you keep batteries installed in the unit even though you’ll be powering it with
the AC adaptor. That way, you’ll be able to continue a performance even if the cord of the AC adaptor
gets accidentally disconnected from the unit.
* Use only the specied AC adaptor (PSA-series).
* If the AC adaptor is connected while power is on, the power supply is drawn
from the AC adaptor.
CHECK indicator
This indicator shows whether an eect is ON/OFF, and doubles as the Battery Check indicator.
The indicator lights when an eect is ON.
* If this indicator goes dim or no longer lights while an eect is ON, the battery is near
exhaustion and should be replaced immediately.
TONE knob
This adjusts the tone of sound. Rotating it clockwise will create sharp sound with
emphasized treble, while turning it counterclockwise will create soft sound with
cut treble.
Pedal Switch
This switch turns the eects ON/OFF.
Thumbscrew
When this screw is loosened, the pedal will open, allowing you to change the
battery.
* For instructions on changing the battery, refer to “Changing the Battery.”

A battery was installed in the unit before it left the factory. The life
of this battery may be limited, however, since its primary purpose
was to enable testing.
5
If you handle batteries improperly, you risk explosion and uid
leakage. Make sure that you carefully observe all of the items
related to batteries that are listed in “USING THE UNIT SAFELY” and
“IMPORTANT NOTES” (supplied on a separate sheet).
5
When operating on battery power only, the unit’s indicator will
become dim when battery power gets too low. Replace the
battery as soon as possible.
5
Batteries should always be installed or replaced before connecting
any other devices. This way, you can prevent malfunction and
damage.

ATTACK knob
This adjusts the intensity of the attack in the picking.
At its clockwise position, the attack sound is retained in each note even in fast
picking, creating drive sound.
SUSTAIN knob
This knob adjusts the sustain time. Rotating this knob clockwise increases
the sustain time. By rotating it counterclockwise, the output level is limited,
therefore the CS-3 works as a limiter.
INPUT jack
This jack accepts input signals (coming from a guitar, some other musical
instrument, or another eects unit).
* The INPUT jack doubles as the power switch.
Power to the unit is turned on when you plug
into the INPUT jack; the power is turned o
when the cable is unplugged.
To prevent unnecessary battery consumption, be
sure to disconnect the plug from the INPUT jack
when not using the eects unit.
