AC Adaptor
(PSA series; sold separately)
Electric Bass
English
Equalizer Control knobs
These knobs allow you to boost or cut the center frequency of 50, 120, 400,
500, 800, 4.5 k or 10 kHz within +/-15 dB.
The BOSS GEB-7 is a 7-band equalizer designed specically for electric bass.
Since it allows for a broad range of frequency settings, even ve string basses can be accommodated.
The unit is designed to provide the optimum Q (equalizer’s bandwidth) for bass for each center frequency. While making it easy to obtain the most delicate of nuances, it also allows for radically unique settings as well.
The GEB-7 allows you to adjust the output level of the equalized sound so it matches the level of the input sound.
OUTPUT jack
Connect an amplier to this jack.

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 specied AC adaptor (PSA-series).
CHECK indicator
This indicator shows whether an eect is ON/OFF, and doubles as the Battery Check indicator.
The indicator lights when an eect is ON.
* If this indicator goes dim or no longer lights while an eect is ON, the battery is near
exhaustion and should be replaced immediately.
* The CHECK indicator shows whether the eect is on or o, and indicates the dierent
functions. It does not indicate whether the power to the device is on or not.
Pedal Switch
This switch turns the eects 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.”

Use of Battery
* A battery is supplied with the unit. The life of this battery may
be limited, however, since its primary purpose was to enable
testing.
* 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).
* 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.
* Batteries should always be installed or replaced before
connecting any other devices. This way, you can prevent
malfunction and damage.
Changing the Battery
1. Hold down the
pedal and loosen
the thumbscrew,
then open the
pedal upward.
* The pedal can be
opened without
detaching the
thumbscrew
completely.
2. Remove the old
battery from the
battery housing,
and remove the snap cord connected to it.
3. Connect the snap cord to the new battery, and place
the battery inside the battery housing.
* Be sure to carefully observe the battery’s polarity (+ versus -).
4. Slip the coil spring onto the spring base on the back of
the pedal, and then close the pedal.
* Carefully avoid getting the snap cord caught in the pedal, coil spring, and
battery housing.
5. Finally, insert the thumbscrew into the guide bush
hole and fasten it securely.
