ZOOM BFX-708
USAGE AND 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:
Please observe the following safety tips and precautions to ensure
hazard-free use of the BFX-708.
• 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 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 BFX-708 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
Avoid using your BFX-708 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 BFX-708 is a precision electronic device, avoid
applying excessive force to the switches and buttons. Also
take care not to drop the unit, and do not subject it to shock
or excessive pressure.
• Alterations
Never open the case of the BFX-708 or attempt to modify
the product in any way since this can result in damage to the
unit.
• Connecting cables and input and output
jacks
You should always turn off the power to the BFX-708 and
all other equipment before connecting or disconnecting any
cables. Also make sure to disconnect all cables and the AC
adapter before moving the BFX-708.
Usage Precautions
• Electrical interference
For safety considerations, the BFX-708 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 BFX-708, as the possibility of
interference cannot be ruled out entirely.
With any type of digital control device, the BFX-708 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 BFX-708. 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 BFX-708
Thank you for selecting the ZOOM BFX-708 (hereafter simply called the "BFX-708"). The
BFX-708 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 compressor/distortion
effects specially designed for bass players, various modulation effects such as chorus and flanger,
reverberation effects such as reverb and delay. In total, you have 48 types of effects readily
available.
• 60 immediately usable patches
A combination of effect modules and parameter settings stored in memory is called a "patch". The
BFX-708 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 BFX-708 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.
• 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
Built-in sampler allows recording of bass guitar sounds or external sources such as a CD player for
up to 6 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
Integrated amp simulator duplicates the acoustic characteristics and cabinet sound of a bass 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 BFX-
708 and to ensure optimum performance and reliability.

Preparations
1Use a monaural cable to connect the bass
to the INPUT jack of the BFX-708.
At this time, the amplifier power switch and the
power switch of the BFX-708 should be OFF.
2Use a monaural cable to connect the
OUTPUT jack of the BFX-708 to the input
of the amplifier.
By using two amplifiers, you can get great
stereo sound from stereo effects. Use a stereo
Y cable to connect the OUTPUT jack to the
two amplifiers.
3To monitor the sound with headphones,
connect the headphones to the OUTPUT
jack.
4Verify that the amplifier is turned off and
that the volume control is turned to
minimum. Also verify that the power switch
of the BFX-708 is set to OFF.
5When using an AC adapter, plug the output
cable from the adapter into the DC 9V jack
on the BFX-708 and plug the adapter into
an AC outlet.
To guard against inadvertently disconnecting
the AC adapter cable, wind the cable once
around the hook on the rear panel of the BFX-
708.
6Turn on power in the order BFX-708 →
amplifier (playback equipment).
7Adjust the volume of the amplifier and the
BFX-708 to a suitable position while
playing the instrument.
The OUTPUT knob of the BFX-708 should be
set to about the 3 o'clock position, and the AMP
SIM knob should be set to the OFF position.
When the BFX-708 is in the bypass state (all
effects are temporarily turned off; see page
10), the output level will be the same as the
input level if the OUTPUT knob is turned fully
clockwise.

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 BFX-708 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-and-
write 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 BFX-708 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 push-
down 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.

When using an active bass guitar or if the signal overloads the circuits of the BFX-708, adjust the
gain as follows. In the factory default condition, the unit is set up for use with a passive bass guitar.

The condition where you call up patches stored in the memory of the BFX-708 and use them for playing your
instrument is called "play mode". This is the condition the unit is in when you turn the power on. The various
operations possible in play mode are described in this section.
In play mode, the panel shows the following information.
1To switch patches in play mode, press one
of the ▼/▲foot switches.
Pressing the ▼foot switch moves to the next
lower patch, and pressing the ▲foot switch moves
to the next higher patch. For example, if you press
the ▲foot switch repeatedly, the unit will switch
patches, banks, and groups as follows.
2To directly switch the bank, use the TYPE
(BANK) ▼/▲keys. This allows you to move
to the next lower or next higher bank.
To quickly move to a patch stored at a distant
location, use the TYPE (BANK) ▼/▲keys together
with the ▼/▲foot switches.
This is not possible while playing a rhythm
pattern.
It is also possible to set up the unit so that only
patches from the USER group or from the
PRESET group are switched. To do this, press
both TYPE (BANK) ▼/▲keys together. With
each push, the group from which patches can
be selected is toggled as follows.
• If you plan to use several patches in a song,
copying them to continuous numbers in the
USER group will make them easy to call up.
For information on copying patches, p.
16
• You can also set up the unit to reserve a
patch and switch to it only after you confirm
the selection. (For details, p. 14.)

The BFX-708 also incorporates a sampler that allows recording for up to 6 seconds. This can
be used not only to record bass 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 bass phrase played by a pro.
1Connect the recording source to the
INPUT jack of the BFX-708.
Before making or changing any connections,
be sure to set the OUTPUT knob to the zero
position. If a cable is plugged in or unplugged
while the OUTPUT knob is turned up, shock
noise may damage the speaker.
2To activate the sampler function, press the
SAMPLER key in play mode.
The sampler goes into the recording standby
mode and the display shows the following
information.
3Turn parameter knob 1 to select "BP"
(BFX-708 effects are not used for
recording) or "EF" (BFX-708 effects are
used for recording).
4Turn parameter knob 2 to select "NML"
(normal playback speed) or "SLW" (slow
playback speed at half tempo without
changing pitch).
5Push the ▲foot switch and start playback
of the external source (CD player or
similar) you want to record, or play the
phrase you want to record.
In this mode, the expression pedal operates as
controller for the recording level.
During recording, the display shows the
indication "RECORDING". The module LEDs on
the panel light up in sequence, to show the
elapsed time.
6To terminate the recording, press the ▼
foot switch. Recording stops, and
playback immediately starts from the
beginning.
During playback, the indication "PLAY" is shown
on the display.

Normally, for editing a patch of the BFX-708, 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".
1To change the sound of a patch in play
mode, turn parameter knobs 1 - 3. The
parameters controlled by the knobs are as
follows.
The actual parameter controlled by the parameter
knob 1 - 3 depends on the patch.
When a knob is turned, the current setting of the
affected parameter is shown on the BANK/PATCH
indicator, and a dot (.) appears at the "EDITED"
position. This indicates that the parameter has
been changed. If the parameter is returned to the
original setting, the dot disappears.
Besides the above parameters, the MODULE
/ keys can be used to change the PATCH
LEVEL parameter.
2To store an edited patch, carry out the
steps for storing( p. 16).
If another patch is called up without storing the
edited patch, the edited contents will be lost.
The Easy Edit function is not available while
using the rhythm pattern.

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;
1 In play mode, press the EDIT (CANCEL) key.
2Use the MODULE / keys to cause the
TOTAL module LED to light up.
3Use the TYPE (BANK) ▼/▲keys to cause
the indication "DIRLOD" (Direct Load) to
appear on the display.
This parameter determines whether the sound is
switched immediately when a patch is selected.
4Turn parameter knob 1 so that the
BANK/PATCH indicator shows "oF".
5Press the EDIT (CANCEL) key once more.
The unit returns to the play mode, and reserving
a patch is now possible. When a new patch is
selected in this condition, the BANK/PATCH
indicator and the patch name on the display are
flashing, but the sound does not change yet.
This shows that the unit is waiting for
confirmation from the user.
To confirm the patch change, press both ▼/▲
foot switches at the same time. The
BANK/PATCH indicator and display indication
stop flashing, and the sound of the new patch
becomes active.
• To return to the original operation mode, set
the DIRLOD parameter to "on".
• The DIRECT LOAD setting is stored
automatically by the unit. There is no need to
perform any steps for storing.

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.
Each patch of the BFX-708 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.
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.
Also within the same module, different effect types will have different parameters.

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.
1In play mode or edit mode, press the
STORE key.
The BFX-708 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).
2Use 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
flashing alternately on the display.
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
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.

Strictly speaking, the PEDAL module is not an effect module. It contains various settings for the expression pedal.
This is a combined delay and hall effect.
* TYPE 4 and 5parameters are identical.
Adjusts delay time in 10-ms steps.
Adjusts delay mix.
Adjusts reverb mix.
This is a combined delay and reverb effect.
This is a special effect that lets you record your bass guitar signal
while playing and reproduce it in various ways.
Selects 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.
Selects playback method for ▼ foot switch.
tS (Trigger One-Shot): Pressing ▼foot switch causes one play
run from start. Pressing ▼foot switch during play stops play.
tL (Trigger Loop): Pressing ▼foot switch causes loop play.
Pressing ▼foot switch during play stops play.
GS (Gate One-Shot): While ▼foot switch is pressed, one play
run from start is performed. Releasing ▼foot switch stops play.
GL (Gate Loop): While ▼foot switch is pressed, loop play from
start is performed. Releasing ▼foot switch stops play.
rS (Retrigger One-Shot): Pressing ▼foot switch causes one play
run from start. Pressing ▼foot switch during play causes restart
from beginning.
Adjusts effect mix.

Effect Types and Parameters
NOTE
TOTAL module
TOTAL is not an independent effect module. Rather it serves to set parameters that affect all patches or the entire BFX-708. You can
switch between the TOTAL 1 and TOTAL 2 pages with the TYPE (BANK) ▼/▲keys.
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.
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 power-
on.
Adjusts input signal gain characteristics.
For details, see page 8.
This parameter applies to all patches. It is automatically stored
when the parameter setting is changed.
TOTAL 2TOTAL 1
Selects module to be assigned to expression pedal.
oF: Off
VL: Volume
dS: COMP•DIST module
Md: MOD module
rv: REV module
Determines how parameter changes when pedal is moved.
UP: Parameter minimum value → maximum value
(forward direction)
dn: Parameter maximum value → minimum value
(reverse direction)
Hi: Current value → maximum value (forward direction)
Lo: Minimum value → current value (forward direction)
Sets minimum value when using expression pedal as volume
pedal (ASSIGN parameter set to "VL").
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.
