ZOOM 504 II ACOUSTIC
The 504 II is a sophisticated multi effect processor for acoustic or
electric guitar with the following features and functions:
• Rich effect palette for acoustic guitar
The 504 II incorporates a wealth of effects specially designed for use with
an acoustic guitar. De-AMP reduces harshness when playing an acoustic
guitar through a guitar amplifier. AIR lends a spacious feeling to the
sound. TOUCH makes picking more uniform and smooth. The 504 II is
also useful as a preamplifier for recording acoustic or electric guitar, and it
offers various patches tuned specially for electric guitar.
• Great for electric guitar too
The built-in simulator transforms the sound of an electric guitar into that of
an acoustic instrument. During a live performance, this makes it a snap to
switch between different sound characteristics.
• Highly effective feedback suppressor
The F.B.SUPPRESSOR function automatically detects the frequencies
where feedback (howling) occurs and attenuates that band. Operation can
be controlled easily with a foot switch.
• Built-in auto-chromatic tuner
The integrated tuning function lets you quickly and precisely tune your
instrument on stage.
• Dual power supply enables operation anywhere
The dual power supply principle 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 8 hours with manganese batteries and 28
hours with alkaline batteries.
• Compatible with foot switch and pedals
An optional foot switch (FS01) or expression pedal (FP01/FP02) can be
connected to the CONTROL IN jack. The foot switch is useful for quickly
detecting the feedback frequency, and the expression pedal allows
adjusting the volume or effect tone in real time.
• Improved successor to 504
While inheriting the sound characteristics of the very successful ZOOM
model 504, the 504 II is even more compact and carries a lower price tag.
What's more, it incorporates the world's first wah effect specifically
designed for acoustic guitar, plus several other novel effects such as the
EMPHASIZER which duplicates the characteristic sound of a resonator.

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:
Features
Play mode/edit mode
The internal status of the 504 II is referred to as the operation mode. The
two major modes are play mode, in which you can select patches and use
them for playing your instrument, and edit mode, in which you can modify
the effects. The [PLAY/EDIT] selector serves for switching between the
play mode and edit mode.
Terms Used in This Manual
This section explains some important terms that are used throughout the
504 II documentation.
Terms Used in This Manual / Using the unit on batteries
Terms Used in This Manual
Effect parameter
The effects of the 504 II consist of a succession of modules that determine
the sound. These individual modules are called the effect parameters. As
shown in the following illustration, the 504 II has 10 different effect
parameters. Changing the setting of an effect parameter is like turning the
control knob on a compact effect, leading to a change in the sound.
Global parameters
Normally, effect parameter settings are stored individually for each patch,
but some effect parameters affect all patches. Such parameters are called
global parameters. The global parameter settings do not change also when
the patch is switched.

Effect type
Some effect parameters comprise several different effects which are
referred to as effect types. For example, the DLY&REV parameter has the
four effect types LARGE, SMALL, DELAY, and DLY+REV. Only one of
these can be selected at a time.
OUT
Using the unit on batteries
1. Turn the 504 II over and open
the cover of the battery
compartment on the bottom.
Press the latch to release it and
then raise the cover.
Insert all batteries with
the same orientation.
Patch
In the 504 II, effects are stored and called up in units referred to as patches.
A patch comprises information about the setting and on/off status of effect
parameters. The memory of the 504 II holds up to 36 patches.
Four IEC R6
(size AA) batteries
Bank
A group of six patches is called a bank. The 504 II manages a total of six
banks, labelled A through F. The patches within each bank are numbered 1
through 6. To specify a patch, the 504 II uses the following format: "A1".
This means that patch number 1 from bank A is selected. Therefore "b6"
would refer to patch 6 from bank b.

Using the Feedback Suppressor
The 504 II incorporates an F.B.SUPPRESSOR that serves for reducing
acoustic feedback by cutting a specific frequency range (feedback
frequency). The F.B.SUPPRESSOR can be used in play mode or edit
mode.
Using F.B.SUPPRESSOR in play mode
If feedback occurs while playing the instrument, the optional foot
switch (FS01) connected to the CONTROL IN jack can be used to
automatically detect the feedback frequency.
1. Insert the plug of the FS01 into the CONTROL IN jack of
the 504 II, then turn power to the 504 II on.
2. Set the [PLAY/EDIT] selector to
"F.B.SUPPRESSOR".
3. Use the [+]/[-] keys to change the display
indication to "SC".
"SC" is the attenuation setting value based on
automatic detection of feedback frequency.
Automatic detection starts when the
F.B.SUPPRESSOR parameter is set to "SC" or set to
off and then on again.
When wishing to retain the "SC" setting also while
the unit is turned off, store the currently selected
patch.

select "SC" again, or press both [ ]/[ ] foot
switches (or the foot switch FS01 connected to the
CONTROL IN jack) twice, to switch the
F.B.SUPPRESSOR parameter off and then on again.
3. If feedback is not satisfactorily reduced by
step 2, set the F.B.SUPPRESSOR parameter
to a value between 1 - 30 that yields the best
reduction.
When wishing to retain the F.B.SUPPRESSOR
parameter setting also while the unit is turned off,
store the currently selected patch.

Using the Expression Pedal (FP01/FP02)
The 504 II is equipped with a CONTROL IN jack designed for
connection of the optional expression pedal FP01 or FP02. The pedal
can be used as volume pedal or as a controller for varying effect
parameters.
For information on parameters that can be adjusted with the expression
pedal, please refer to pages 26 - 29.
1. Plug the cable from the FP01/FP02 into the CONTROL IN
jack of the 504 II, and then turn the 504 II on.
NOTE
If the FP01/FP02 is plugged into the CONTROL IN jack while the 504
II is already on, malfunction may occur. Be sure to turn on the 504 II
only after connecting the expression pedal.
Restoring Factory Defaults
The 504 II comes with 36 preprogrammed patches. These factory
default patches can be restored also if they were overwritten by patches
created by the user.
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, plug the appropriate
cable into the INPUT jack (or DC 9V jack).
The indication "AL" flashes on the display.
To perform All Initialize
2. Press the STORE key once more.
2. Select the patch in play mode, and
move the expression pedal back

instrument.
Depending on the program content of the patch, the volume or
effect parameter will change.
The expression pedal can also be used in edit mode to control the
volume or effect parameter.
NOTE
Restoring Factory Defaults
Using the Expression Pedal
All patch settings are returned to the factory default condition, and
the unit switches to play mode. To cancel All Initialize, press the [-]
key.
All user-created patches will be lost when performing All Initialize.
Use this function with care.
To perform Factory Recall
2. Use 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 [-] key. The unit will switch
to the play mode at this point.

parameter, the content of the other three parameters changes as follows.
When ACOUSTIC
is selected
This section describes all parameters and their setting values.
Parameter on/off
Expression pedal
A pedal icon (
) in the listing indicates
that the parameter can be controlled with
the expression pedal (FP01/FP02) when
the value is selected.
If there is no parameter marked with a
pedal icon selected in the entire
patch, the expression pedal operates
as a volume pedal.
Except for the TYPE parameter,
all parameters have an "
"
setting which disables the
parameter. (The effect is the
same as when both [ ]/[ ]
foot switches are pressed
together in edit mode.)

AIR
DOUBLING
Creates a doubling effect like two players playing the same tune with
a slight shift. Higher values result in larger shift between original
sound and effect sound.
Simulates the ambient character of sound picked up with a
microphone. Higher values result in greater simulated distance
between the guitar and the microphone.
PEDAL DOUBLING
oF
TOUCH
Sets the AIR parameter to OFF.
Allows using the expression pedal (FP01/FP02) connected to the
CONTROL IN jack to adjust the intensity of the DOUBLING effect.
This effect aligns the picking touch. Higher values result in distinct
notes even with soft picking.
PEDAL TOUCH

Usage Precautions
• Electrical interference
For safety considerations, the 504 II 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 504 II, as
the possibility of interference cannot be ruled out entirely.
With any type of digital control device, the 504 II 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 504 II. 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.
Troubleshooting
No power
Low volume
Refer to "1. Power-on" on
page 8.
Pickup with low output is being used? See page 6.
Patch does not change
Battery life is short
Check whether patch call
method is set to pre-select
(see page 16).
Are manganese batteries being used? Continuous
operation time is 28 hours with alkaline batteries
but only 8 hours with manganese batteries. The
use of alkaline batteries is recommended.
