ZOOM GFX-1
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 the wrong
way, serious injury or 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 GFX-1.
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 GFX-1 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 GFX-1
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 GFX-1 since this
can cause electric shock.
• Do not place naked flame sources, such
as lighted candles, on the GFX-1 since
this can cause fire.
• The GFX-1 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 GFX-1 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-1.
Alterations
Never open the case of the GFX-1 or
attempt to modify the product in any way
since this can result in damage to the unit.
Volume
Do not use the GFX-1 at a loud volume
for a long time since this can cause
hearing impairment.

ZOOM GFX-1
The GFX-1 is a sophisticated multi-effect processor for guitar with the
following great features.
●
Superior performance
The GFX-1 provides a palette of 34 built-in high-quality effects,
including a wide variation of distortion settings and flexible
modulation effects. Up to nine effects can be used simultaneously. In
performance and features, the GFX-1 far surpasses anything in its
class.
●
Sturdy case and smooth operation feel
The metal body and large foot switches of the GFX-1 are designed to
withstand the rigors of use on stage. The intuitive operation of the unit
is derived from the highly popular ZOOM 606. Dedicated selectors for
the most important distortion effects make the unit a snap to use.
Controlling distortion type and intensity during a performance is
smooth and easy.
●
Built-in auto-chromatic tuner
The integrated auto-chromatic tuning function is tailored for the needs
of the guitarist and can be used on stage.
●
Compatible with expression pedal
Connecting an optional expression pedal makes it easy to adjust effect
depth or volume with your foot during play. Whether you choose pedal
wah or gutsy pitch bend, the range of available sounds is on a par with
top-range units.
●
Dual power supply principle allows use anywhere
Besides the AC adapter, the unit can also be powered from four IEC
R6 (size AA) batteries. Continuous operating time on batteries is
approximately 7 hours with manganese batteries and 24 hours with
alkaline batteries.

ZOOM GFX-1
This section explains some important terms that you will find in this manual.
●
Effect module
As shown in the illustration below, the effect sound of the GFX-1 is
created by routing the signal through a series of different effects. Each
of these effects is called an effect module.
In addition to effect modules such as DRIVE (distortion), MOD/
PITCH (modulation), or DLY/REV (delay and reverb), you can also
use the ZNR (Zoom Noise Reduction) and amp simulator
simultaneously. Parameters such as effect intensity can be adjusted for
each module, and modules can be switched on and off as needed.
●
Effect type
Each effect module of the GFX-1 contains a variety of effects in the
same general family. These are called effect types, and you can select
one of these at a time. For example, the MOD/PITCH module
comprises the effect types chorus, flanger, pitch shifter, etc.
●
Effect parameter
Each effect module has various parameters that control how the effect
operates. By adjusting the parameters for each module, you have a
considerable amount of control over the final sound.
●
Patch
In the GFX-1, effects are stored and called up in patches. A patch
contains information about module on/off settings, selected effect
types, and effect parameter settings. The GFX-1 can store 40 patches
in its internal memory.
●
Bank
A combination of 4 patches is called a bank. The GFX-1 has a total of
10 banks which are labelled A through J. The patches in each bank are
numbered 1 through 4. To select a patch, you specify the bank and the
patch number. A1 selects patch 1 in bank A, and F4 selects patch 4 in
bank F.
