cycle through the effects in the order shown below. When an eff ect is selected, its icon will blink.
1)DYNA
(Dynamics & Pickup Modeling)
These are dynamics-type effects such as compressor and auto-wah that modify the tone, and
pickup modeling effects.
2. Editing each effect
For each effect, you can select the effect type
and set its parameter values.
Effects that are turned “OFF” will automatically
be turned on if you press the ENTER/REC but-
ton or use the ▲/▼ buttons to select the effect
type.
For details on the effect types and parameters,
refer to Effect P ar ameters (p.30). Renaming the
program and writing the program are also performed here.
2)AMP (Amp Modeling)
The fifteen types BTQ CLN–FUZZ are guitar amps,
and the ten types VALVE–UKMAJOR are bass amps.
SYNTH is a synth for both guitar and bass.

mately one second if you’ve selected a guitar
model, or “bA” if you’ve selected a bass model.
The amp type selected by the amp modeling
selector can be selected and edited even without entering Edit mode.
When you use the Amp
Modeling selector to select an amp, the PX4D will
automatically select the most appropriate cabinet
model and turn it on.
The VOLUME control knob can be used to ad-
just the V OLUME even when the amp modeling
effect is “OFF.”
3)CAB (Cabinet Modeling)
This simulates the acoustical characteristics of
the amp’s cabinet. This is especially effective
when you are not using an amp (e.g., when using headphones, or when connecting to a mixer, hard-disk recorder , or audio de vice). The eleven types 1X8TWD–4X12VIN are guitar amp cab-
inets, and the twelve types LA 4X10–COMBI are
bass amp cabinets.
26
The value display will indicate “Gt” for approximately one second if you’ve selected a guitar
amp cabinet, or “bA” if you’ve selected a bass
amp cabinet.
You are free to use a guitar AMP with a bass
CAB, or a bass AMP with a guitar CAB.
4)MOD (Modulation & Filter Effect Modeling)
These are modulation and filter-type effects
such as chorus, flanger, phaser, and pitch
shifter.

7)NR (Noise reduction)
Use the Value dial to adjust the depth of the
noise reduction that is applied.
Increasing this value will produce more noise
reduction. Normally you will adjust this so that
you do not hear obtrusive noise when the strings
are lightly muted.
If the NR value is raised excessively, the sound
may be cut off prematurely, depending on the
device that is connected. If this occurs , reduce
the value.
Adjust the NR level as suitable for your guitar,
bass, or pickup.
8)RENAME
Here you can specify a name for each program.
The following characters can be used: space,
0–9, A–Z, “, ‘, ❋, +, -, /.

9)WRITE
Here you can write (store) a program that you
created.
Use the Value dial to select the writing destination (User programs only). When you do so, the
name of the program that currently occupies the
writing destination will be displayed briefly.
If you decide not to write, press the √ (or ®)
button to select a different screen.
When you press the ENTER/REC button, the edited program will be written into memory.
When the program has been written, the LCD will
indicate “COMPLT” for appro ximately one second.

3. Reloading the factor y programs
While holding down the RHYTHM button and
the ▲ button, turn on the power. The LCD will
ask “RELOAD?”
If you press the ENTER/REC button, the factory-set programs will be re-loaded into the user
program area. The display will indicate “RE-
LOAD”, “VERIFY”, “COMPLT” for a short time,
and then the power-on screen will appear.
Never turn off the power during the reload operation.
If you decide not to reload, press the EXIT but-
ton while the “RELO AD?” indication is still sho wn.
The factory programs will not be reloaded; the
normal power-on screen will appear, and the
PX4D will be in Play mode.
Be aware that if you reload the factory programs, the user programs and any settings that
are remembered when the power is turned off
(master level etc.) will all be rewritten.
Troubleshooting
If the PX4D does not operate as you expect,
please check the follo wing points first. If this does
not resolve the problem, contact your dealer.
1.Power does not turn on.
•Are batteries installed? Alternatively, is the
correct AC adapter connected to an AC outlet?
2.No sound
•Are your guitar or bass, amp and/or headphones connected to the correct jacks?
• Is your amp turned on and set correctly?
• Are any cables broken?
• Is the master level of the PX4D set to “0” or
to a low level?
• The VOLUME control knob may have been
turned down.
• Is the PX4D muted?
Be aware that if all effects are off, the chain
display will disappear, and it will not be possible to distinguish Bypass or Mute from the
LCD display.
• Is the volume of your guitar turned down?
3.The volume from the device connected to
the AUX jack is too loud or too soft, or cannot be heard.
• Adjust the output level of the connected device.
Make connections to the headphone jack of
the device, instead of to its line output.
• Are you in Phrase Trainer mode?
Exit Phrase Trainer mode.
• Are you using a connection cable with a builtin resistor?
4.Effects do not apply
• Is the PX4D bypassed? (the effect chain will
be blinking)
• Are the effects used in the program turned
on?
5.Tuner does not work.
• Is the PX4D bypassed or muted?

sound, and mixes it with the original sound to add a sense

two or more strings are played simultaneously, or when lowpitched strings are played.
