Caution
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 GFX-3.
Power requirements
Since power consumption of this unit is fairly high, we
arning
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 GFX-3 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,
arning
avoid using your GFX-3 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
arning
the GFX-3 since this can cause electric shock.
• Do not place naked flame sources, such as lighted
candles, on the GFX-3 since this can cause fire.
• The GFX-3 is a precision instrument. Do not exert
undue pressure on the keys and other controls. Also take
Caution
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
Caution
You should always turn off the power to the GFX-3 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 GFX-3.
Alterations
Never open the case of the GFX-3 or attempt to modify
arning
the product in any way since this can result in damage to
the unit.
Volume
Do not use the GFX-3 at a loud volume for a long time
Caution
since this can cause hearing impairment.
Usage Precautions
• Electrical interference
For safety considerations, the GFX-3 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 GFX-3, as
the possibility of interference cannot be ruled out entirely.
With any type of digital control device, the GFX-3 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 GFX-3. 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.

ZOOM GFX-3
Introduction
Thank you for selecting the
the following features.
●
Versatile array of effects
The Variable Architecture Modeling System (VAMS) developed by ZOOM adapts the
internal configuration of the unit to achieve exactly the desired sound. The GFX-3
provides 50 choices, ranging from distortion and modulation effects to spatial sound
processing.
●
Full complement of distortion effects
20 distortion type effects not only recreate the characteristics of famous vintage amps
but also duplicate the sound and operation of renowned compact effects and pedals.
The built-in acoustic simulator makes an electric guitar sound like an acoustic
instrument.
●
120 ready-to-use patches
Effect module setting combinations can be stored as patches. The GFX-3 offers 60
user patches which can be freely modified, plus 60 preset patches. Together, these 120
settings let you make great music straight away.
●
Mode-free editing for creative flexibility
The selectors and keys arranged on the panel let you directly access any effect.
Because there is no need for mode switching, editing can be performed quickly even
during a performance. The built-in pedal makes things even simpler by letting you
vary effect parameters in real time. The GFX-3 is a powerful tool for enhancing any
live performance.
●
Energizer produces powerful sound
The Energizer lets you match the output of the GFX-3 to the playback system. Enjoy
powerful, dynamic sound even with a small guitar amp or an audio system with flat
response.
●
Designed for use on stage
The metal chassis of the GFX-3 can withstand the rigors of use on stage. Stability is
excellent, and the dual power supply allows the unit to be powered either from an AC
adapter or from batteries. With one set of alkaline batteries, the unit will operate
continuously for up to 11 hours.

Quick Guide
This section explains the basic operation steps, allowing you to use the unit right away.
Selecting a patch
To select a patch, press one of the foot
switches [1] - [3] whose LED is not lit.
The single effects (effect modules) in the GFX-3
can be combined, and parameter settings for each
effect can be changed to achieve a desired sound.
Such a combination of effects with certain
parameter settings is called a patch. Patches are
always called onto the panel in banks of three, and
the foot switches [1] - [3] are used to select the
patch.
Group
Bank number
To switch to a patch in another group or
bank, use the BANK [Q]/[W] keys and
then the foot switches [1] - [3].
Patches are organized in user groups (U, u) which
can be modified, and preset groups (A, b) which are
read-only. Each group comprises ten banks
numbered from 0 to 9, and each bank has three
patches.
The BANK [Q]/[W] keys select groups and banks
in the order U0 - U9, u0 - u9, A0 - A9, b0 - b9.
* Pressing foot switches [1] and [2] together has the
same effect as pressing the BANK [W] key, and
pressing foot switches [2] and [3] together has the
same effect as pressing the BANK [Q] key.
For a detailed explanation of patch switching, see page
