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 G2.
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 G2 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 G2 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 G2 since this can cause electric shock.
•Do not place naked flame sources, such as lighted candles,
on the G2 since this can cause fire.
• The G2 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 G2 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 G2.
Alterations
Never open the case of the G2 or attempt to modify the
product in any way since this can result in damage to
the unit.
Volume
Do not use the G2 at a loud volume for a long time
since this can cause hearing impairment.
Usage Precautions
Electrical interference
For safety considerations, the G2 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 G2, as the possibility of
interference cannot be ruled out entirely.
With any type of digital control device, the G2 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 G2. 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.

Features
Thank you for selecting the ZOOM G2 (hereafter simply called the "G2"). The G2 is a multi effect
processor with the following features and functions.
●
Latest processing technology for outstanding performance
96 kHz / 24 bit sampling (with 32 bit internal processing) assures excellent sound quality. Frequency
response remains flat up to 40 kHz, and input-converted signal-to-noise ratio is an amazing 120 dB,
demonstrating the high level of performance achieved by the G2.
●
Versatile palette of effects including new creations
Out of a total of 54 effects, up to nine (including ZNR) can be used simultaneously. The high-quality
choices provided by the G2 include distortion effects that simulate the tones of famous amps and effects
pedals, 6-band guitar EQ and delay effects with "hold" controloperated by foot switch.
●
Great for live performances and direct recording
The distortion effect module provides two different algorithms for each of its 17 effect types, one for live
performance and one for direct recording. Depending on the on/off setting of the CABINET & MIC
effect which simulates amp cabinet sound and mic characteristics, the most suitable algorithm is
automatically selected, giving you the best sound for any application.
●
Integrated rhythm functions and auto-chromatic tuner
A number of rhythm patterns using realistic PCM drum sounds are provided. This is convenient for use
as a metronome during individual practice or to provide a simple rhythm part for a quick session. An
auto-chromatic tuner for guitar is also built right into the unit, allowing you to easily tune your
instrument also at home or on stage.
●
Sophisticated user interface
The combination of a rotary type selector and three parameter knobs make the effect editing process
intuitive and quick. The mute interval when switching patches has been reduced to less than 5
milliseconds. Seamless patch changing is now a reality.
●
Dual power supply principle allows use anywhere
The G2 can be powered from four IEC R6 (size AA) batteries or an AC adapter. Continuous operating
time on batteries is approximately 7.5 hours with alkaline batteries.
●
Easy operation with foot switch and expression pedal
An optional foot switch (FS01) or expression pedal (FP01/FP02) can be connected to the CONTROL IN
jack. The foot switch is convenient for quickly switching effect programs, setting the tempo for the
rhythm function, or switching delay hold on and off. The expression pedal can be used to adjust the
volume or the tonal quality of an effect in real time.
Please take the time to read this manual carefully so as to get the most out of the unit and to ensure
optimum performance and reliability.

Terms Used in This Manual
This section explains some important terms that are used throughout the G2 documentation.
■
Effect module
As shown in the illustration above, the G2 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 comprising compressor effects
(COMP), amp simulator/distortion effects (DRIVE),
and modulation/special effects (MOD/SFX), the G2
also provides a module for ZNR (ZOOM Noise
Reduction). Parameters such as effect intensity can
be adjusted for each module individually, and
modules can be switched on and off as desired.
■
Effect type
Within some effect modules, there are several
different effects which are referred to as effect types.
For example, the modulation/SFX effect module
(MOD/SFX) comprises chorus, flanger, pitch shifter,
delay, 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.
In the G2, effect parameters are adjusted with the
parameter knobs 1 – 3. Similar to the knobs on a
compact effect, these change aspects such as tonal
character and effect intensity. Which parameter is
assigned to each knob depends on the currently
selected effect module and effect type.
■
Patch
In the G2, 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 G2 holds up to 80 patches
(including 40 patches which allow read/write).
■
Bank and area
A group of ten patches is called a bank. The memory
of the G2 comprises a total of eight banks, labelled A
to d and 0 to 3. Banks A – d form the user area
which allows read/write. Banks 0 to 3 are the preset
area containing read-only patches.
The patches within each bank are numbered 0
through 9. To specify a patch of the G2, you use the
format "A1" (patch number 1 from bank A), "06"
(patch number 6 from bank 0), etc.
■
Play mode/edit mode
The internal status of the G2 is referred to as the
operation mode. The two major modes are "play
mode" in which you can select patches and use them
for playing your instrument, and "edit mode" in
which you can modify the effects. The module
selector serves for switching between the play mode
and edit mode.

Switch to bypass or mute
Setting the G2 to the bypass state
In play mode, press both [W]/[Q] foot
switches together briefly and release.
Setting the G2 to the mute state
In play mode, press both [W]/[Q] foot
switches together and hold for at least 1
second.
When you press both [W]/[Q] foot switches together while
playing your instrument, the bypass/mute condition is
activated. However, the sound may change momentarily
just before the condition is activated. This is because the
G2 switches to the next higher or lower patch when one of
the foot switches is pressed slightly earlier. (When you
cancel the bypass/mute condition, the original patch
number will be active again.)
This kind of behavior is not a defect. It is due to the very
high speed at which the G2 responds to patch switching.
To prevent the sound change caused by the above
condition, do not produce sound with your instrument until
the bypass/mute condition is fully established.
Play the string to tune
Play the open string to tune,
