Making connections
When connecting an external device (ie-guitar
amp, stereo, ac adapter, etc)be sure to turn the
unit off.
*1 Do not block the transmission window when
using the infrared transmitter function.
*2 Be sure to use only the specified AC adapter
(DC4.5V
).
*3 If a CD player or other audio source is con-
nected to AUX jack, you can play along on
your guitar with a tape, etc. However the vol-
ume must be adjusted on the connected de-
vice.
*4 Connecting cables are sold separately.
*5 PX4s output jack is stereo. If you use a stan-
dard mono cable to connect it to a guitar amp
etc., only the L (left) output will be heard.
*6 PX4s output level and sound quality will vary
depending on which headphones are used.
We recommend using good quality low imped-
ance headphones, 32 Ohms or less with a
sensitivity rating near 100dB/mW or above.
Many headphones sold for use with portable
CD or cassette players will work just fine.
12
Initial Settings
1. When you finish making connections, set the
power switch in the ON position. (This set-
ting is referred to as Play mode.)
Use the / buttons to select a program.
2. Set the input level switch to a position appro-
priate for the output level of your guitar.

Quick Edit
In each mode (except when Mute/Bypass or Key
Lock are active), you can use the Amp Model-
ing selector to quickly change the amp model-
ing type, or use the control knobs to adjust the
gain, tone, or volume of amp modeling. When you
move a control knob, the parameter name and
value will appear for several seconds in the val-
ue display. If the setting matches the original set-
ting, the ORIG icon will light.
The Delay Time of Delay Modeling can also be
set by pressing the TAP button twice at the de-
sired interval (except when in Rhythm & Bass
mode). To check the Delay Time that was speci-
fied, press and hold the TAP button for two sec-
onds or longer.

the TUNE/BYPASS button once again.
You can also return to Play mode by pressing the
EXIT button.
Bypass or Mute can also be entered from modes
other than Play mode.
4.Tuner
The tuner will operate when you bypass or mute.
Play a single string on your guitar. The LCD will
show the note name and the calibration. If the
pitch is more than a semitone higher than the

If METRONM (metronome) is selected as the
rhythm pattern, there will be no bass notes, and
this screen will not appear.
When using Chain Patterns, the Bass Key set-
ting will be ignored.
4. Rhythm & Bass Reverb Level
Use the Value dial to set the amount of Rhythm &
Bass sound that will be sent to reverb modeling.
The same effect as for the guitar is used for re-
verb. This parameter has no effect if you have
selected a program that does not use reverb
modeling, or if the reverb effect level is "0."
Chain Pattern settings
These parameters are added only if you select
"CHAIN" as the rhythm pattern. Press the EN-
TER/REC button to access the Chain Parame-
ter Select screen. Use the /® buttons to se-
lect the location (1...8) for which you want to
change the pattern, and use the Value dial to
select the pattern (p.40) that will be used at that
location. Use the / buttons to specify the bass
key of the selected pattern.
Up to 8 patterns can be connected. If you want to
create a chain of 7 or fewer patterns, select "PTN

Press the ENTER/REC button to exit the Chain
Pattern Select screen.
19
Phrase Trainer mode
An audio source from the AUX jack or a phrase
you play on your guitar can be recorded, and
played back repeatedly as a loop.
This provides a convenient way to practice by
playing along with the repeating phrase.
You can slow down the playback speed without
affecting the pitch, which can help you to learn
difficult phrases.
If you select "JAM" as the recording mode, the
rhythm you specified in Rhythm & Bass mode
will be recorded simultaneously with the guitar
input, and looped.
1.Select the recording mode
In Play mode (except during bypass/mute or key
lock), Rhythm & Bass mode, or AUX Pitch mode,
press the PHRASE TRAINER button to enter
Phrase Trainer mode.

Phrase Trainer icon will blink. In this screen, the
PX4 will be ready to record.
The recording mode will cycle through the fol-
lowing choices each time you press the PHRASE
TRAINER button.
AUX Records only the AUX input
GUITAR Records only the guitar sound
AUX+GTR Records both the AUX input and
guitar
JAM Records the guitar together with
the rhythm that was last selected
in Rhythm & Bass mode
Use the value dial to select the recording time
(for "JAM," the number of measures).
8 Approximately 7.9 seconds
16 Approximately 15.8 seconds
32 Approximately 31.7 seconds
1, 2, 4, 8 Number of measures
20
If the recording mode is "JAM," the recording
quality will be set automatically, based on the tem-
po and the specified number of measures.
If you select a long recording time (16 or 32),
the audio quality of the recording will be lower.
If the tempo of the rhythm is extremely slow, it
will not be possible to record a large number of
measures. Please re-specify the tempo in
Rhythm & Bass mode (maximum length is ap-
proximately 31.7 seconds)
Start playback on your CD or other audio source,
and at the point where you wish to begin record-
ing, press the ENTER/REC button. Recording
will begin.
If the recording mode is "JAM," recording will
begin after two measures of playback.
If, after recording, you want to change the re-
cording mode or recording time, press the
PHRASE TRAINER button while playback is
paused.
The recorded content will be lost when the power
is turned off.
2.Recording
When you begin recording, the recording time will
be indicated as a numerical value and by a value
graph.
Recording
time display
When you want to stop recording, press the EN-
TER/REC button or the [
]. Recording will
stop, and loop playback will begin automatically.
If you do not stop recording, recording will con-
tinue until the selected recording time has
elapsed, and loop playback will begin automati-
cally.
If the recording mode is "JAM," recording will end
automatically at the specified number of mea-
sures, and will switch to loop playback.
The phrase will be recorded and played back in
mono.
