• PATCH
A group of the settings for a certain effect type is called a PATCH. The 504 comes with 24 preset
patches which can be changed (edited) by the user.
• BANK
The 504 calls up patches in sets of four, called a "bank".
The 504 has memory
capacity for 24 patches.
At the factory, these are
programmed with
recommended settings.
The user can Edit and Store
any patch, and also restore
the factory settings.
The patches of banks A
through d for acoustic
guitar are designed for
line output to a mixer or
similar. When using a
guitar amplifier, it is
recommended to adjust
the De-Amp parameter.
What Are Banks and Patches?
PATCH LIST
Configuration of Patches
Controls, Functions and Connections
The patches of the 504 are created using the nine parameters listed below. A parameter is an
element that determines a certain aspect, such as the sound character or the effect intensity.
Parameters can be altered by the user as desired, and a set of changed parameters can be stored as
a patch for later recall.
Global parameters are common to all patches.
For an explanation of the function of each parameter, please refer to section "11. Editing
Patches".

TUNER indicator
• Bypass(Mute)/Tuner mode
Indicator shows that tuning function is active and also serves to show the correct fine
tuning position.
• Edit mode
Indicator flashes when LEVEL parameter (overall patch level) is selected.
• BATTERY EMPTY WARNING display
When the unit is powered from the battery and the battery is running low, this
indicator begins flashing at a faster rate than in Edit mode. In such a case, replace the
battery as soon as possible.
STORE key
When the contents of patches are to be stored, this key is used for putting the unit in
store standby status and to execute the store function.
• Setting of direct load function
When the STORE key is pressed for at least 1 second during Play mode (during
performance), the direct load function can be switched on or off. [For details, see 10
Patch Switching (Application: Direct Load OFF).]
EDIT key (for creating your own patches)
This key serves to toggle between the Play mode and Edit mode (mode for creating
patches to suit your taste).
In Edit mode, this key can be used to select the effect parameters you wish to change.
Also, when the effect parameter LEVEL is selected, press this EDIT key to return
from the Edit mode to the Play mode.
• Setting of bank hold function
When the EDIT key is held down for at least 1 second in Play mode, the bank hold
function is turned on or off. [For details, see 9 Patch Switching (Application: Bank
Hold ON).]
INPUT jack
Serves for connection of an acoustic or electric guitar. Choose the HIGH or LOW
input, according to the output level of the pickup.
• HIGH:
For electric guitars with single-coil pickups or acoustic guitars with magnetic
pickups.
• LOW:
For electric guitars with humbucking or active type pickups, or for electroacoustic
guitars.
When the unit operates on batteries, the INPUT jack doubles as a power switch.
Plugging in a shielded cable turns the 504 on. To prevent draining the battery, unplug
the cable when the unit is not in use.
DC IN (AC adapter) jack
Serves for connecting an AC adapter (Zoom AD-0006) which delivers 9 VDC, 300
mA with a "center minus" plug configuration. The 504 is powered on by plugging
an AC adapter into this jack.
CONTROL IN jack
The optional FP01 expression pedal or FS01 foot switch can be connected here,
for external control of the 504.
When the expression pedal FP01 is connected, the pedal controls the output level.
When the foot switch FS01 is connected, the switch turns the F.B.SUPPRESSOR
function on and off. For a detailed explanation, please refer to section "12. Effect
Parameters".
NOTE:
Before connecting or disconnecting the FP01 or FS01, make sure that the 504 is switched
off. Otherwise malfunction can occur.
DISPLAY
Displays information required to operate the 504.
• Play mode
Displays the selected bank (A-F) and patch (1-4).
• Edit mode
Displays the value of the selected effect parameter.
• Bypass(Mute)/Tuner mode
Shows the pitch of the input signal.
PARAMETER CURSOR indicator
• Play mode
The currently used effect module lights.
• Edit mode
The indicator lights up for the currently used effect module, and the indicator
flashes for the effect module that is turned off. Also, the indicator for the effect
module selected for editing flashes.
• Bypass(Mute)/Tuner mode
Indicators function as tuning meter.
VALUE +/- keys
• Play mode
The keys serve for bank switching.
• Edit mode
The keys serve for changing the effect parameter.
• Bypass(Mute)/Tuner mode
The keys serve for setting the tuner reference pitch (calibration).
PATCH UP (right)/DOWN (left) pedals
• Play mode
The pedals serve for patch switching. Pressing both pedals simultaneously
activates the Bypass(Mute)/Tuner mode.
• Edit mode
The pedals serve for selecting effect parameters. Pressing both pedals
simultaneously turns the currently selected effect module on or off.
• Bypass(Mute)/Tuner mode
Pressing either pedal cancels the Bypass(Mute)/Tuner mode to return to Play
mode.
OUTPUT jack
This jack is for the output signal from the 504. You can connect either a single
guitar amplifier, using a monaural shielded cable, or two guitar amplifiers, using a
Y-type stereo shielded cable, or a pair of stereo headphones. If the volume level is
low when using headphones, use headphones with low impedance (32 ohms or
less).

Global parameters
Global parameters are common to all
patches. Their effect does not change
when switching patches. The global
parameter settings are stored in the
memory of the unit, along with patches.
