SAFETY PRECAUTIONS
In this manual, symbols are used to highlight warnings and
cautions for you to read so that accidents can be prevented.
The meanings of these symbols are as follows:
This symbol indicates explanations about
extremely dangerous matters. If users
ignore this symbol and handle the device
incorrectly, serious injury or death could
result.
This symbol indicates explanations about
dangerous matters. If users ignore this
symbol and handle the device incorrectly,
bodily injury and damage to the equip-
ment could result.
Please observe the following safety tips and precau-
tions to ensure hazard-free use of the G1u.
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G1u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 malfunc-
tion, avoid using your G1u 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 G1u since this can cause electric
shock.
• Donotplacenaked flame sources, such aslighted
candles, on the G1u since this can cause fire.
• The G1u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 G1u and
all other equipment before connecting or disconnect-
ing any cables. Also make sure to disconnect all con-
nection cables and the power cord before moving the
G1u.
Alterations
NeveropenthecaseoftheG1uorattempttomodify
the product in any way since this can result in dam-
age to the unit.
Volume
Do not use the G1u at a loud volume for a long time
since this can cause hearing impairment.
Usage Precautions
Electrical interference
For safety considerations, the G1u has been designed to pro-
vide maximum protection against the emission of electro-
magnetic radiation from inside the device, and protection
fromexternalinterference.However,equipmentthatisvery
susceptible to interference or that emits powerful electro-
magnetic waves should not be placed near the G1u, as the
possibility of interference cannot be ruled out entirely.
With any type of digital control device, the G1u included,
electromagnetic interference can cause malfunctioning and
can corrupt or destroy data. Care should be taken to mini-
mize the risk of damage.
Cleaning
Useasoft,dryclothtocleantheG1u.Ifnecessary,slightly
moisten the cloth. Do not use abrasive cleanser, wax, or sol-
vents (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.

SAFETY PRECAUTIONS / Usage Precautions Terms Used in This Manual
This section explains some important terms that are used throughout the G1u manual.
• Effectmodule
As shown in the illustration above, a patch in the
G1u can be thought of as a combination of up to
eightsingleeffects.Eachsucheffectisreferredto
as an effect module.
• Effecttype
Some effect modules have several different effects
which are referred to as effect types. For example,
the MODULATION module is comprised of
chorus, flanger, pitch shifter, 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
or simply 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 G1u, effect module combinations are stored
and called up in units referred to as patches. A patch
is comprised of information about the on/off status
and effect parameter settings used in each module.
•Bank
A group of ten patches is called a bank.
The memory of the G1u is comprised of a total of
20 banks, labeled with letters A to J (user-editable
banks)andnumbers0to9(read-onlypreset
banks), as shown in the illustration at top right.
• Mode
The internal status of the G1u is referred to as the
operation mode. The function of keys and controls
differs, depending on the respective mode. Modes
of the G1u include play mode for selecting and
playing patches, rhythm mode for playing a
rhythm pattern, edit mode for modifying effects,
and store mode for saving patches.
When the batteries are
getting low, the indication
"bt" appears on the display.
When operating the G1u on
batteries, it is advisable to
disconnect the guitar cable
plug from the [INPUT] jack
when not using the unit, to
conserve battery power.
3. Close the cover of the
battery compartment.

1. Turn the G1u over and open
the cover of the battery
compartment on the bottom.

indication "bP" appears on the display, release the
switches within 1 second.
•SettingtheG1utothemutecondition

[W]/[Q]footswitchestogether.Waituntilthe
indication "bP" on the display changes to "Mt" and
then release the switches within 1 second.
· If you keep pressing the foot switches for more than 1
second after the indication "Mt" has appeared, the
looping function (gp. 12) will be activated.
· The bypass or mute condition cannot be activated
when the unit is in edit mode (gp. 14).
Switch to bypass or mute
1
To use the tuner function of the G1u, the built-in effects must be bypassed (temporarily turned off)
or muted (original sound and effect sound turned off). Play the open string to tune, and adjust the pitch.
To fine-adjust the reference pitch of the G1u tuner,
turn the [VALUE] knob in the bypass/mute
condition.
When you turn the knob, the current reference pitch
is shown for a time on the display. The default setting
is40(centerA=440Hz).
While the reference pitch is shown, turn the
[VALUE]knobtoadjustthevalueintherangefrom
35–45(centerA=435to445Hz).
When power is turned off and on again, the reference
pitch setting will be reset to 40 (center A = 440 Hz).

Patch change at bypass/mute
When you press both [W]/[Q] foot switches
together while playing your instrument, the
sound may change momentarily just before
the bypass/mute condition is activated.
This is because the G1u 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 behavior is not a defect. It is due to the
very high speed at which the G1u 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.
