ZOOM GFX-4
Introduction
Thank you for selecting the ZOOM GFX-4 (simply called the "GFX-4" in this manual). The GFX-4 is a sophisticated Guitar Effects Processor with the following features.
● Versatile array of effects
The Variable Architecture Modeling System (VAMS) adapts the internal configuration of the unit
to achieve exactly the desired sound. The GFX-4 includes vintage effects such as famous
overdrive, distortion, compressor, and phaser sounds of the seventies and eighties, as well as ultra-
modern processing functions. Up to eight effects can be freely combined for simultaneous use.
● Great choice of distortion sounds
In addition to traditional guitar amplifier characteristics, the GFX-4 uses modeling technology to
duplicate the sound and operation feel of celebrated compact distortion effects. Well-proven
combinations such as booster + distortion or compressor + overdrive can be established quickly and
easily. By combining distortion effects with the built-in amp and cabinet simulator, you can get
optimum sound also for line out recording.
● Designed to get the best out of any guitar
The ACTIVE NORMAL switch provides quick and precise impedance and level matching for any
guitar. Whether you have a passive pickup or use an active pickup or integrated preamp, your
instrument will sound its best.
The OUTPUT MONO jack uses analog bypass with a mechanical switch, so that the output in
bypass mode is not subject to any kind of digital signal processing.
● Simple and intuitive operation
Thanks to three FX panels, the GFX-4 can be operated like a series of compact effects. Foot
switches are convenient for turning effects on and off, and sound parameters can be adjusted
quickly with rotary controls. The Easy Edit function is a snap to use also during a performance.
With the GFX-4, playing your instrument and editing the sound is one seamless operation.
● Extensive patch library
A combination of effects can be assigned a name of up to six characters and stored as a patch in the
memory of the unit. There are 60 user patches (4 groups x 5 banks x 3 patches) which can be freely
rewritten, plus 60 preset patches that make the unit ready to use right out of the box. The
possibilities are almost endless.
● Great for use on stage
The GFX-4 incorporates an expression pedal that can serve as real-time effect controller or volume
pedal. The easy-to-read 6-character display and 2-character indicator make it easy to check patch
names and settings at a glance, which is helpful during a live gig.
In order to get the most out of this sophisticated product, please read this manual carefully before use. We recommend that you keep the manual at hand for future reference.
Introduction
● Module
A "module" is a section that works like a stand-alone
compact effect device for tailoring certain aspects of
the sound. In the GFX-4, you can use the six modules
COMP/OD/ENV, DRIVE, EQUALIZER, PEDAL,
MODULATION, and DELAY/REVERB as well as the
ZNR (Zoom Noise Reduction) + AMP SIM (Amp
Simulator) simultaneously.

ZOOM GFX-4
This section explains some important terms that are used throughout the GFX-4 documentation.
Terms Used in This Manual
I
● Effect types and parameters
Within each effect module, there are various effect
types which are specific processing functions. The
various settings of the currently selected effect type are
called parameters. By selecting an effect type and
varying the parameters, you can create a new effect.
● Patch/group/bank
Effect module combinations and effect parameter
settings are stored in memory as "patches". The GFX-4
can hold a total of 120 patches. These are divided into
60 user patches which are read/write, and 60 read-only
preset patches. Both the user patches and preset patches
are divided into four groups (A, b, C, d). Each group
has 5 banks numbered from 0 - 4, and each bank has 3
patches. To use a patch in the GFX-4, you first call up
the bank and then use the three foot switches 1 - 3 to
select the patch.
● Modes
Operation of the GFX-4 is divided into five main
modes, as listed below.
• Program mode
This is the basic operation mode of the GFX-4. The
unit is always in this mode after power is turned on.
The mode is used for switching patches and for editing
the currently selected patch.
• Manual mode
This mode lets you switch modules on and off,
operating the unit in the same way as a compact effect
with the knobs and foot switches on the FX panels.
• Store mode
This mode serves for storing patches edited in program
mode or manual mode in the memory of the unit. It
also allows changing the store positions of user
patches.
• Bypass/mute mode
When the GFX-4 is in the bypass condition, effect
processing is temporarily turned off and only the
original sound is heard. In the mute mode, all sound is
turned off and the built-in chromatic tuner can be used.
• Special mode
This mode serves for making amp simulator and ZNR
settings, patch name and patch level settings, and for
returning the GFX-4 to the factory default condition.
● RTM (real-time modulation)
The RTM function allows use of the expression pedal
to adjust DRIVE, MODULATION, or
DELAY/REVERB module parameters or the volume in
real time. For example, you might use the pedal during
a performance to vary the reverb mix balance or adjust
wah intensity with your foot.
The module, effect type, and parameter, as well as the
parameter change direction can be set separately for
each patch.

■ When using effects
The OUTPUT MONO jack supplies only the left-channel
signal. This is suitable for example for connection to a
guitar amp or another effect device.
■ When using Bypass
When the GFX-4 is in bypass mode, the analog input
signal appears unchanged at this jack, due to the action of
a switching relay. (This means that there is absolutely no
sound quality change caused by digital processing.)
Note that the expression/volume pedal and the MASTER
LEVEL knob have no effect on the signal in this
condition.
When wishing to use the volume pedal and master level control also in bypass mode, use the OUTPUT STEREO jack.

About the Mono Output
The GFX-4 has two output jacks labeled OUTPUT STEREO and OUTPUT MONO. When the OUTPUT MONO jack is
used, a mechanical relay switch operates in bypass mode, which results in true bypass (analog bypass where the signal is
not subject to any kind of digital processing).
To use the output of the GFX-4 in mono, connect the OUTPUT MONO jack. To use the output of the GFX-4 in stereo, connect a Y cable to the OUTPUT STEREO jack. * When connecting the GFX-4 to a hi-fi system
or a multi- track recorder (MTR), activating the built-in amp simulator (➝ p. 7) is recommended).
