Getting Ready
Connecting the Equipment
1
Turn down the volume of the
connected device
PHONES jack
You can connect a set of
headphones here.
* To prevent malfunction and equipment failure, always turn down the
volume, and turn o all the units before making any connections.
OUTPUT jack
Connect these to your bass amp or
mixer. If using a mono connection,
use only the L/MONO jack.
4
Turn on the power of the
amp(s)
3
Connect your bass
INPUT jack
Connect your bass. 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.
2
AUX IN jack
Use a stereo-mini plug to
connect your audio player.
Use your audio player’s volume
control to control the volume of
OUTPUT jacks and PHONES jack.
Connect your equipment to the
OUTPUT jack(s)
USB COMPUTER port
Use a USB cable
to connect to a
computer and
exchange audio
data between the
GT-1B and the
computer (p. 8).
DC IN jack
This jack is for connecting
an AC adaptor (BOSS PSA
series; sold separately).
Use only the specied AC
adaptor (PSA series), and
connect it to an AC outlet
of the correct voltage.
Do not use any other AC
adaptor, since this may cause
malfunction.
* Before turning the unit on/o, always be sure to turn the volume
down. Even with the volume turned down, you might hear some
sound when switching the unit on/o. However, this is normal and
does not indicate a malfunction.
Installing the Batteries
Install four alkaline batteries (AA, LR6) in the battery compartment located on the bottom of the unit.
* When turning the unit over, be careful so as to protect the buttons and knobs from damage. Also, handle the unit
carefully; do not drop it.
* 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” (separate sheet “USING THE
UNIT SAFELY” and Owner’s manual (p. 12)).
* 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.
* To prevent malfunctions or accidents, install or replace the batteries before connecting the unit to other equipment.
* “BATTERY LOW” will appear on the display if the batteries are low. Replace them with new ones.
CTL2, 3/EXP2 jacks (Connecting to External Pedals)
You can control various parameters by connecting an expression pedal
(EV-30, Roland EV-5: sold separately) or a footswitch (FS-5U, FS-6, FS-7: sold

For details on the settings, refer to “Settings for CTL1, EXP1, and an External
Pedal” (p. 9).
