ZOOM 607 BASS
Features
Features
The 607 is a sophisticated multi-effect processor for bass guitar
with the following great features.
• Outstanding performance
The 607 provides a palette of 35 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 terms of performance and features, the 607 far surpasses
everything in its class.
• Built-in expression pedal
The integrated pedal makes it easy to adjust effect depth or volume
during play. Use it to adjust gain, get a gutsy pitch bend, or perform
many other advanced functions.
• Smooth operation feel
The intuitive operation of the unit is derived from the highly
popular ZOOM 506 II. Dedicated selectors for the most important
distortion effects make the 607 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 to the
needs of the bass guitarist and can be used on stage.
• Dual power supply enables operation anywhere
The dual power supply allows the unit to be powered either from an
AC adapter or from four IEC R6 (size AA) batteries. Continuous
operation time on batteries is 7 hours with manganese batteries and
24 hours with alkaline batteries.

SAFETY PRECAUTIONS
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:
This symbol indicates explanations
about extremely dangerous
matters. If users ignore this
symbol and handle the device the

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 607.
About power
• 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.
• If the unit is not to be used for a long
time, disconnect the AC adapter from
the outlet.
Battery operation
• Use four IEC R6 (size AA) 1.5 V
batteries (alkaline/manganese).
• The 607 cannot be used for recharging.
Pay close attention to the labelling of
the battery to make sure you choose the
correct type.
• If the 607 is not to be used for an
extended period of time, remove the
battery 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 607 in environments
where it will be exposed to:
• Extreme temperature
• High humidity or moisture
• Excessive dust or sand
• Excessive vibration or shock
Handling
• The 607 is a precision instrument.
Except for the foot switches, do not
push other parts with your feet or
subject them to strong force.
• Take care that no foreign objects (coins
or pins etc.) or liquids can enter the unit.
• Be sure to turn the power to all
equipment off before making
connections.
• Before moving the unit, turn the power
off, and disconnect all cables and the
AC adapter.
Alterations
Never open the case of the 607 or attempt
to modify the product in any way since
this can result in damage to the unit.

These terms refer to the operation state of the 607. The mode is
selected with the PLAY/EDIT selector. In play mode, you can select
the effects for playing, and in edit mode, you can change the effect
settings.

Basic Terms
Basic Terms
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 607 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 607 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 607, 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 607 can store 42 patches in its internal
memory.
■Bank
A combination of 6 patches is called a bank. The 607 has a total of 7
banks which are labelled A through G. The patches in each bank are
numbered 1 through 6. To select a patch, you specify the bank and the
Bottom of 607
Latch
Four IEC R6 (size AA)
batteries
Battery
compartment cover
1. Turn the unit over, push the latch
of the battery compartment
cover, and lift the cover up.
3. Close the battery compartment cover.
Make sure that the latch snaps shut.
2. Insert four fresh IEC R6 (size AA)
batteries into the battery compartment.
All four batteries must face in the same
direction.
NOTE
• When a dot (.) flashes on the display, the batteries are almost
exhausted. Replace them as soon as possible.
• When not using the 607, you should disconnect the cable plugged
into the INPUT jack, to prevent draining the batteries.

Adjusting the Expression Pedal
The expression pedal of the 607 is adjusted for optimum operation at
the factory, but sometimes, readjustment may be necessary. If the
action of the pedal seems to be insufficient, or if a large change occurs
even if the pedal is only lightly pushed, adjust the pedal as follows.
1. While holding down the PEDAL ASSIGN key,
turn the unit on.
The indication "dn" flashes on the display.
2. With the expression pedal fully raised, press the STORE
key.
The display indication changes to "UP".
3. Push the expression pedal fully down and then lift your
foot off the pedal.
When you release your foot, the pedal goes back a little.
4. Press the STORE key.
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
module 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.

Restoring the Factory Defaults
Restoring the Factory Defaults
The 607 comes with 42 recommended patches (factory default
patches). Even if you overwrite any of these patches, you can restore
the original contents of the patch at any time.
There are two ways of restoring factory defaults. "All Initialize" returns
the entire set of patches to the original condition. "Factory Recall"
restores a specific patch to the original condition.
1. While holding down the STORE key, turn the unit on.
The indication "AL" flashes on the display.
■To perform All Initialize
2. Press the STORE key once more.
All patch settings are returned to the factory default condition, and
the unit switches to play mode. To cancel All Initialize, press the
VALUE [-] key.
All user-created patches will be lost when performing All Initialize.
Use this function with care.
■To perform Factory Recall
2. Use the [W] / [Q] foot switches to select the
patch you want to return to the original
condition.
The specified bank and patch number flashes on the display.
During Factory Recall, the VALUE [+] / [-] keys cannot be used to
switch the bank only.
3. Press the STORE key once more.
The settings of the specified patch are returned to the factory default
condition.
If desired, repeat steps 2 and 3 to restore other patches. To terminate
the Factory Recall operation, press the VALUE [-] key. The unit will
