death could result.
This symbol indicates explanations about dangerous 
matters. If users ignore this symbol and handle the 
device the wrong way, bodily injury and damage to 
the equipment could result.
Please observe the following safety tips and precautions to 
ensure hazard-free use of the B1/B1X. 
Power requirements
Since power consumption of this unit is fairly high, we 
recommend the use of an AC adapter whenever 
possible. When powering the unit from batteries, use 
only alkaline types. 
[AC adapter operation] 
• Be sure to use only an AC adapter which supplies 9 V DC, 
300 mA and is equipped with a "center minus" plug 
(Zoom AD-0006). The use of an adapter other than the 
specified type may damage the unit and pose a safety 
hazard. 
• Connect the AC adapter only to an AC outlet that supplies 
the rated voltage required by the adapter. 
•When disconnecting the AC adapter from the AC outlet, 
always grasp the adapter itself and do not pull at the cable. 
• During lightning or when not using the unit for an 
extended period, disconnect the AC adapter from the AC 
outlet.
[Battery operation]
• Use four conventional IEC R6 (size AA) batteries 
(alkaline). 
• The B1/B1X cannot be used for recharging. 
•Pay close attention to the labelling of the battery to make 
sure you choose the correct type. 
•When not using the unit for an extended period, remove 
the batteries from the unit. 
• If battery leakage has occurred, wipe the battery 
compartment and the battery terminals carefully to 
remove all remnants of battery fluid. 
•While using the unit, the battery compartment cover 
should be closed. 
Environment 
To prevent the risk of fire, electric shock or 
malfunction, avoid using your B1/B1X in environments 
where it will be exposed to:
• Extreme temperatures 
• Heat sources such as radiators or stoves
• High humidity or moisture 
• Excessive dust or sand 
• Excessive vibration or shock
Handling 
•Never place objects filled with liquids, such as vases, on 
the B1/B1X since this can cause electric shock.
•Do not place naked flame sources, such as lighted candles, 
on the B1/B1X since this can cause fire.
• The B1/B1X is a precision instrument. Do not exert undue 
pressure on the keys and other controls. Also take care not 
to drop the unit, and do not subject it to shock or excessive 
pressure. 
•Take care that no foreign objects (coins or pins etc.) or 
liquids can enter the unit. 
Connecting cables and input and output 
jacks 
You should always turn off the power to the B1/B1X 
and all other equipment before connecting or 
disconnecting any cables. Also make sure to disconnect 
all connection cables and the power cord before moving 
the B1/B1X. 
Alterations 
Never open the case of the B1/B1X or attempt to 
modify the product in any way since this can result in 
damage to the unit. 
Volume 
Do not use the B1/B1X at a loud volume for a long time 
since this can cause hearing impairment. 
Usage Precautions
Electrical interference 
For safety considerations, the B1/B1X has been designed to 
provide maximum protection against the emission of 
electromagnetic radiation from inside the device, and protection 
from external interference. However, equipment that is very 
susceptible to interference or that emits powerful 
electromagnetic waves should not be placed near the B1/B1X, 
as the possibility of interference cannot be ruled out entirely.
With any type of digital control device, the B1/B1X included, 
electromagnetic interference can cause malfunctioning and can 
corrupt or destroy data. Care should be taken to minimize the 
risk of damage.
Cleaning 
Use a soft, dry cloth to clean the B1/B1X. If necessary, slightly 
moisten the cloth. Do not use abrasive cleanser, wax, or solvents 
(such as paint thinner or cleaning alcohol), since these may dull 
the finish or damage the surface.
Please keep this manual in a convenient place for 
future reference.

When operating the B1/B1X on batteries, it is advisable
to disconnect the guitar cable plug from the [INPUT] 
jack when not using the unit, to conserve battery power.
Push the cover in until the

Terms Used in This Manual 
This section explains some important terms that are used throughout the B1/B1X documentation.
■
Effect module 
As shown in the illustration above, the B1/B1X can
be thought of as a combination of several single
effects. Each such effect is referred to as an effect
module. 
In addition to modules such as DRIVE and
MODULATION/DELAY, the B1/B1X also provides
a module for noise reduction and amp simulation
(ZNR/AMP). 
Parameters such as effect intensity can
be adjusted for each module individually, and
modules can be switched on and off. 
■
Effect type 
Some effect modules have several different effects
which are referred to as effect types. For example,
the MODULATION/DELAY module comprises
chorus, flanger, and other effect types. Only one of
these can be selected at a time.
■
Effect parameter 
All effect modules have various parameters that can
be adjusted. These are called effect parameters.
When thinking of an effect module as a compact
effect, the parameters change the tone and effect
intensity similar to the knobs on the device.
■
Patch 
In the B1/B1X, effect module combinations are
stored and called up in units referred to as patches.
A patch comprises information about the on/off
status of each effect module, about the effect type
used in each module, and about effect parameter
settings. The internal memory of the B1/B1X can
store up to 80 patches.
■
Bank and area 
A group of ten patches is called a bank. The
memory of the B1/B1X comprises a total of eight
banks, labelled with letters A to d and numbers 0 to
3. Banks A – d are the user area which allows read/
write. 0 – 3 form the preset area of read-only
patches.
The patches within each
bank are numbered 0
through 9. To specify a
patch of the B1/B1X, you
use the format "A1" (patch
number 1 from bank A),
"06" (patch number 6 from
bank 0), etc. 
■
Mode 
The internal status of the B1/B1X is referred to as
the operation mode. In "play mode" you can select
patches and use them for playing your instrument.
In "edit mode" you can modify the effects, and there
is also a "rhythm mode" in which you can make
settings for the rhythm function. The module
selector serves for switching between these three
modes.
