prevented. The meanings of these symbols are as
follows:

Warning

Caution

Please observe the following safety tips and precautions to ensure
hazard-free use of the GFX-707.

• Power requirements

Warning

• Environment

Caution

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.

Since power consumption of this unit is fairly high, we
recommend the use of an AC adapter whenever possible.
When powering the unit from a battery, use only an alkaline
type.

[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.

• 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-707 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.

Avoid using your GFX-707 in environments where it will be
exposed to:

• Extreme temperature

• High humidity or moisture

• Excessive dust or sand

• Excessive vibration or shock

• Handling

Since the GFX-707 is a precision electronic device, avoid
applying excessive force to the switches and buttons. Also

Caution

take care not to drop the unit, and do not subject it to shock
or excessive pressure.

• Alterations

Never open the case of the GFX-707 or attempt to modify
the product in any way since this can result in damage to the

Caution

unit.

• Connecting cables and input and output
jacks

You should always turn off the power to the GFX-707 and
all other equipment before connecting or disconnecting any

Caution

cables. Also make sure to disconnect all cables and the AC
adapter before moving the GFX-707.

Usage Precautions

• Electrical interference

For safety considerations, the GFX-707 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-707, as the possibility of
interference cannot be ruled out entirely.

With any type of digital control device, the GFX-707 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-707. 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-707

Introduction

Thank you for selecting the ZOOM GFX-707 (hereafter simply called the "GFX-707"). The
GFX-707 is a sophisticated multi-effect device with the following features and functions:

• Large variety of built-in effects

Four separate effect modules (single/combined effects) can be used at the same time, together with
ZNR (Zoom Noise Reduction) and the built-in amp simulator. Effects include analog distortion,
various modulation effects such as chorus and flanger, and reverberation effects such as reverb and
delay. In total, you have a choice of 48 types of effects.

• 60 immediately usable patches

A combination of effect modules and parameter settings stored in memory is called a "patch". The
GFX-707 has room for 30 patches that are read-only and 30 that can be freely modified by the user.
So you have a total of 60 patches readily available. Patches are organized in banks (A - F, 0 - 5),
each with five patches. It is even possible to assign a distinctive name of up to 6 characters to each
patch.

• Designed for use on stage

The GFX-707 will operate continuously for up to 14 hours on one set of alkaline batteries. The large
display showing patch names is easy to read at a distance, and the built-in expression pedal is great
for enhancing any performance. For extended use, the unit can also be powered by an AC adapter.

Introduction

• Rotary knobs allow speedy parameter editing

When editing a patch, the three knobs on the top panel let you change parameters with a quick and
direct feel. Even during a performance, fine-tuning an effect is no problem at all. The edited patch
can be stored for later use.

• A first in this class: built-in rhythm section

A high quality PCM sound source creates realistic rhythm patterns that are handy for practicing or
for small jam sessions. You can choose from as many as 45 rhythm patterns.

• 6-second sampler

Another advantage is the integrated sampler with a recording duration of up to six seconds. It even
allows half-speed playback without altering the pitch. This feature comes in handy when copying
phrases.

• Jam Play

With a simple foot switch operation, you can record and play a phrase of up to 2 seconds during a
gig. This is great for creating scratch effects such as used by DJs, doing reverse playback or
producing other special effects.

• Integrated amp simulator

Simulates the cabinet sound of a guitar amplifier for a dynamic sound also when sending the line
output to a mixer or recorder.

Please take the time to read this manual carefully, in order to get the most out of your GFX­707 and to ensure optimum performance and reliability.

Altering an effect with the pedal

Selecting the effect sound (patch)

A collection of effect modules, each with
distinct parameter settings, is called a patch.
The GFX-707 has memory capacity for 60
patches which are immediately available for
use. These are divided into two groups of 30
patches each. The PRESET group comprises
read-only patches that cannot be changed by
the user. The USER group contains read-and­write patches that can be freely overwritten by
the user.
Each patch is given a patch name of up to 6
characters, and patches are organized in
banks (A - F, 0 - 5) and patch numbers (1 - 5).

[ Patches, groups and banks ]

To alter an effect in real time, move the
expression pedal while playing your
instrument with the GFX-707 in play mode.

The aspect of the patch that is changed by the
expression pedal can be programmed for each
patch. To get a feel for this, select various patches
and try out the pedal to see what it does.

Push the expression pedal fully down

The expression pedal also incorporates a push­down switch that allows on/off control of a preset
effect. The effect that is switched by the push-down
switch can be programmed for each patch.

Using the Sampler Function

NOTE

The GFX-707 also incorporates a sampler that allows recording for up to 6 seconds. This can
be used not only to record guitar sounds but also for external sources such as a CD player.
The data are stored in the memory of the unit and can be played easily using the foot
switches. A recorded phrase can also be played at half the original speed without changing
the pitch. This is convenient for example to study how a fast guitar phrase played by a pro.

Using the Easy Edit Function

Normally, for editing a patch of the GFX-707, you set the unit to edit mode, call up the target
parameter, and change the setting. However, it is possible to use the parameter knobs 1 - 3 in
play mode to change certain effect parameters. This is called "Easy Edit".

1 To change the sound of a patch in play

mode, turn parameter knobs 1 - 3. The
parameters controlled by the knobs are as
follows.

• The sampler function cannot be used at the
same time as the rhythm function or the Jam
Play function.

• While using the sampler function, the MOD
module and REV module included in a patch
cannot be used. (These modules are set to
off, regardless of what the original setting of
the patch is.)

• The recorded contents of the sampler are
automatically erased when the sampler
function is terminated.

Reserving the Next Patch (DIRECT LOAD)

In the factory default condition, patches are switched as soon as you make the selection, resulting
in an immediate change in the sound. This is called "Direct Load". If you want to change to a distant
patch (for example from patch A1 to patch E5), all the intermediate patches will briefly change the
sound, which may not be desirable. In such a case, you can reserve the patch and cause the patch
change to be delayed until confirmed by you. This function is activated as follows;

Altering the Sound of a Patch (Edit Mode Operation)

The edit mode allows you to freely alter the parameters that make up a patch, so that you can create your own patches.
This section describes the operation steps.

Patch Configuration

Each patch of the GFX-707 consists of several effects (effect modules), as shown in the illustration below. A patch is
a combination of modules, each with their distinct parameter settings.

SAMPLER

Patch

COMP•DIST AMP SIMZNR EQ MOD REV

PATCH LEVEL

Within each module, there are several effects which are called effect types. For example. the REV (reverb) module
comprises effect types such as HALL, ROOM, and PP-DLY (ping-pong delay).
The elements that determine the sound of a patch are called effect parameters. Each module has several effect
parameters, whose value can be adjusted with the parameter knobs 1 - 3.

HINTHINT

Also within the same module, different effect types will have different parameters.

Basic Edit Mode Steps

Altering the Sound of a Patch (Edit Mode Operation)

1 In play mode, select the patch you want to

edit.

Patches for editing can be selected from either
the USER group or the PRESET group.
However, the PRESET group does not allow
storing. When you have altered a patch from the
PRESET group and want to store it, you must
select a location in the USER group.

2 Press the EDIT (CANCEL) key.

The GFX-707 switches to the edit mode.
Immediately after the edit mode is activated, the
TOTAL module will be selected.

adjust the parameters 1 - 3 of the currently
selected module.

When one of parameter knobs 1 - 3 is turned,
the name of the corresponding parameter
appears on the display and the current value on
the BANK/PATCH indicator.

For example, if the effect type ROOM of the REV
module is selected, the parameter knobs 1 - 3
will adjust the following parameters.

The GFX-707 returns to the play mode. A dot (.)
appears at the "EDITED" position of the
BANK/PATCH indicator, to indicate that the
patch has been edited.

Storing and Copying Patches

Unless you store an edited patch in the memory of the unit, the edited contents will be lost (the
patch will revert to its original condition) when you select another patch. If you have created a
patch you like, do not forget to store it. It is also possible to store an existing patch in another
location, thereby creating a copy. By copying several patches you want to use in a song to
adjacent numbers in the USER group, you can easily call them up during a performance.

1 In play mode or edit mode, press the

STORE key.

The GFX-707 enters the store standby
condition. If the STORE key is pressed while
using the rhythm function, the rhythm output is
stopped and the unit then enters the standby
condition. When storing an edited patch, be
sure to change the patch name. This is done
with the TOTAL module ( p. 20).

2 Use the TYPE (BANK) ▼/▲ keys and ▼/▲

foot switches to select the store target
(copy target).

If you do not specify the store target, the original
bank/patch number becomes the store target.

When you change the store target bank/patch
number, the changed portion on the
BANK/PATCH indicator flashes. The indication
"STORE?" and the store target patch name are

16

flashing alternately on the display.

PATCH NAME

3 To execute the patch store (copy) process,

press the STORE key once more.

Storing is carried out, and the unit returns to the
play mode. To abort the store process, press
the EDIT (CANCEL) key before step 3.

• The PRESET group is read-only. If a patch

NOTE

from the PRESET group was selected and
the STORE key is pressed, the store target
automatically becomes "A1". Change the
bank/patch number as required.

• When store (copy) is carried out, the previous
patch in the target is overwritten (erased). If
that patch was edited, its contents cannot be
restored. However, it is possible to restore a
selected patch or all patches from the USER
group ( p. 23) to the factory defaults.

Effect Types and Parameters

ZNR/EQ (Zoom Noise Reduction/Equalizer) module

This module contains a 4-band equalizer for making tone adjustments. The equalizer has only one effect type, but because there are
many parameters, it is divided into two pages titled EQ P1 and EQ P2. (Use the MODULE / keys to switch between pages.) This
module also comprises the ZNR settings.

ZNR

The original noise reduction developed by Zoom cuts noise
during performance pauses without impairing the sound quality.

Adjusts ZNR sensitivity. The recommended approach is to set the

Effect Types and Parameters

tS (Trigger One-Shot):

Pressing ▼ foot switch causes one play

run from start. Pressing ▼ foot switch during play stops play.

TOTAL module

TOTAL is not an independent effect module. Rather it serves to set parameters that affect all patches or the entire GFX-707. You can
switch between the TOTAL 1 and TOTAL 2 pages with the TYPE (BANK) ▼/▲ keys.

TOTAL 2TOTAL 1

Specifies input positionParameter 1
Selects charactersParameter 2

Parameter knobs 1 and 2 let you input or edit a patch name. Knob
1 specifies the character input position (indicated by the flashing
part of the display), and knob 2 selects the alphanumeric
character to be input at that position.

PATLVL 1 – 30Parameter 3

Sets final patch level. Level adjustment is performed with
parameter knob 3. A value of 25 corresponds to unity gain.

Switches Direct Load function on and off. When "on", the sound
changes immediately when the patch is switched (default). When
"oF", reading in the new patch is delayed until confirmed by the
user.
This parameter applies to all patches. It is stored automatically
when the parameter setting is changed.

Switches Bank Hold function on and off. When "oF", repeatedly
pressing the ▲ foot switch cycles through all patches and banks,
such as A1 → A2 → A3 → A4 → A5 → B1. When "on", the
bank is fixed and patches are switched only within the bank, such
as A1 → A2 → A3 → A4 → A5 → A1.
This parameter applies to all patches. It is reset to "oF" at power­on.

Adapts characteristics of built-in amp simulator to usage
environment of unit. When GFX-707 is connected to guitar
amplifier, use "AP". For connection to line-level equipment such
as mixer or recorder, use "Ln".
This parameter applies to all patches. It is reset to "AP" at power­on.

When using the expression pedal as a volume pedal, the
volume changes from the MINVOL value to the maximum
value in the forward direction, regardless of the MODE
parameter setting.

Parameters 1 and 2 can be set for each patch and are stored
when the patch is stored. Parameter 3 applies to all patches
and is automatically stored when the setting is changed.

For information on adjusting parameters with the expression
pedal, see page 22.

ZOOM GFX-707

Using the Jam Play Function

Besides its regular sampler, the GFX-707 incorporates a Jam Play feature that records and plays a guitar phrase of up
to 2 seconds. This allows hold delay, and the phrase can also be played in reverse. The direction and speed of
playback can be controlled with the expression pedal, letting you achieve a "scratch" effect such as used by DJs. To
use Jam Play, select a patch for which the effect type of the REV module is set to JAM, and set the STYLE
parameter (playback method) and TRG/GT parameter (foot switch function) as desired.

1 Select the patch to use with Jam Play.

2 Activate edit mode, and select JAM as

effect type for the REV module ( p. 15).
Verify that the REV module is ON.

3 Turn parameter knob 1 and select the

STYLE parameter (playback method for
recorded phrase).

nM (Normal): Play in normal direction.
rS (Reverse): Play in reverse direction.
SC (Scratch): Use expression pedal to play with

scratch type effect. From center position, pedal
controls either forward or reverse playback.

5 Move to the PEDAL module and assign the

expression pedal to the REV module (
p. 22).

6 Store the patch and return to the play

mode.

21

In play mode, when a patch where JAM Play
can be used is selected, the REV and PEDAL
module LEDs are flashing.

7 Push down the expression pedal fully.

The GFX-707 enters the Jam Play mode and
goes into the recording standby condition. The
indication "JP" is shown on the BANK/PATCH
indicator.

The function of the ▼ foot switch and expression
pedal depends on the STYLE parameter and
TRG/GT parameter setting.

When "nM" or "rS" is selected as STYLE
parameter, the expression pedal can be used to
adjust the level of the playback signal.

To record and play a new phrase, repeat steps
8 - 10.

Controlling an Effect With the Pedal

8 While playing your instrument, press the ▲

foot switch when you want to start
recording.

As opposed to the regular sampler function, the
signal recorded for Jam Play always is
processed by the currently selected effects.

9 To stop recording midway, press the ▼

foot switch. Alternatively, after 2 seconds,
recording stops automatically.

10

Use the ▼ foot switch or the expression

pedal to control play/stop of the recorded

11

To terminate the Jam Play mode, push the
expression pedal once more fully down or
press the EDIT (CANCEL) key.

Also after terminating the Jam Play mode, the
most recent recorded phrase is temporarily
retained by the unit and can be used again
when a patch is selected for which Jam Play is
enabled. If Jam Play is enabled for both
patches, it is also possible to switch between
patches while playing the recorded phrase.

When the regular sampler is used or when the
unit is turned off, the phrase is cleared.

phrase.

Controlling an Effect With the Pedal

The expression pedal of the GFX-707 can be used to control the volume or parameters of the COMP•DIST, MOD,
and REV modules in real time.

1 In edit mode, use the MODULE / keys

to cause the PEDAL module LED to flash.

When wishing to control a parameter with the
expression pedal, the parameter must first be
assigned to the pedal in edit mode.

2 Use the parameter knob 1 to select the

assign target for the expression pedal.
Parameter 1 of the PEDAL module is the
ASSIGN parameter.

The following targets can be selected: "VL"
(Volume), "dS" (COMP•DIST module), "Md"
(MOD module), "rv" (REV module). When a
module to which the pedal is assigned is called
up, the indication "Pd" appears on the
BANK/PATCH indicator.

The parameter that is actually controlled is
predetermined for every effect type in the
module. This parameter is indicated by a pedal
mark in the description on pages 17 through 20.

3 Use parameter knob 2 to select the way

the parameter changes when the pedal is
moved.

Parameter 2 is the MODE parameter that
determines the range and direction of the
change caused by the expression pedal.
Available settings are "UP", "dn" (Down), Hi
(High), Lo (Low).

While the stored patch is selected, move the
expression pedal. The parameter assigned to
the pedal in edit mode should change.

6 To switch the ON/OFF status of a module

assigned to the pedal, push the expression
pedal fully down.

In play mode, pushing the expression pedal fully
down switches the ON/OFF status of a module.

• There is one exception to the above
behavior. If a patch is selected for which Jam
Play ( p. 21) is active, pushing the
expression pedal fully down will activate Jam
Play mode and cause the GFX-707 to go into
the recording standby condition.

• When using the expression pedal as a
volume pedal, pushing the pedal fully down
has no effect other than raising the volume.

All Initialize/Factory Recall

The All Initialize/Factory Recall function is a special function that lets you reset the GFX-707 to the condition in
which it was originally shipped. When All Initialize is performed, all patches in the USER group and all other
settings of the unit are returned to the default condition. Factory Recall can be used to reset specific patches in the
USER group to the default settings.

1 Turn power to the GFX-707 on while

keeping the STORE key depressed.

The indication "ALINIT" flashes on the display.

• To perform All Initialize → Continue with step 2

• To perform Factory Recall → Use the ▼/▲
foot switches and TYPE (BANK) ▼/▲ keys to
select the patch (from the USER group) that
you want to return to the factory default
condition.

2 Press the STORE key once more.

All Initialize or Factory Recall is carried out. If All
Initialize was carried out, the unit automatically
returns to the play mode.

Important: When All Initialize is executed, the
contents of all patches stored by the user will
be overwritten (erased). When wishing to
cancel All Initialize/Factory Recall, press the
EDIT (CANCEL) key before step 2.

Adjusting the Expression Pedal

The expression pedal of the GFX-707 uses a highly reliable optical sensor mechanism. The pedal is adjusted for
optimum operation at the factory, but sometimes, readjustment may be necessary. If on/off switching is not
performed when the pedal is fully pushed down, or if on/off switching occurs even if the pedal is only lightly pushed,
adjust the pedal as follows.

1 Turn power to the GFX-707 on while

keeping the SAMPLER key depressed.

The indication "MIN" flashes on the display.

2 With the expression pedal fully raised,

press the STORE key.

The display indication changes to "MAX".

3 Push the expression pedal fully down and

then lift your foot off the pedal (the pedal
goes back a little). Press the STORE key at
this point.

ZOOM GFX-707

The adjustment is completed, and the unit
returns to the play mode.

The point where the STORE key is pressed in
step 3 determines the on/off switching point. If
you want the pedal to perform on/off switching
with a lighter touch, push the key at a
somewhat higher position of the pedal.
