FEATURES
• The BOSS GEB-7 is a 7-band equalizer designed specifically for electric bass.
• Since it allows for a broad range of frequency settings, even five 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.

1. AC Adaptor Jack

Accepts connection of an AC Adaptor (optionally available BOSS PSA-Series). By
using an AC Adaptor, you can play without
being concerned about how much battery
power you have left.
* You may find that it is a good idea to keep a
battery installed in the unit even while using
6
an adaptor. That way your playing won’t be
disrupted even if the adaptor is accidentally
disconnected.-
* If you are going to use an AC adaptor, be sure
to use the specified unit (BOSS PSA-Series).
Use of any other adaptor may result in damage, malfunction or electric shock.
Also, if you are not going to be using it for an
extended period of time, disconnect the AC
adaptor from the AC outlet.
2. CHECK Indicator
This indicator shows whether an effect is
ON/OFF, and also doubles as the Battery
Check indicator.
The indicator lights when an effect is ON.
If this indicator goes dim or no longer lights
while an effect is ON, the battery is near
exhaustion and should be replaced immediately.
3. OUTPUT Jack
The output jacks are used to connect the
unit to amplifiers or other devices.
4. Pedal Switch
This switch turns the effects ON/OFF.
5. Thumbscrew

instructions on how to replace the battery,
please refer to “CHANGING THE BATTERY”.
6. INPUT Jack
This jack accepts input signals (coming
from a bass guitar, some other musical
instrument, or another effects unit).
* The INPUT jack also serves as the power
switch. Power is turned on whenever a plug is
inserted into the INPUT jack, and is turned off
when the plug is disconnected. When not
using the unit, you should disconnect any
cord connected to the INPUT jack.
