1. Introduction
The modes of the AX1500G
The AX1500G has three modes: Play mode, Individual mode, and Phrase Trainer mode.
Play mode is the mode in which you can select a program and play it. When the power is first
turned on, you will always be in this mode. You can select from a total of 96 programs that use
high-quality effect models: 48 preset programs, and 48 user programs that allow you to freely edit
the settings to create your own sounds. In addition, you can switch between effect channels A and
B within each program.
With the factory settings, the user programs contain the same data as the preset programs.
Individual mode the mode in which you can use the foot switches (the program switches and
expression pedal switch) to individually turn each effect block on/off as you play. In this mode
you can switch between effect channels A and B, but cannot switch between programs.
Use Play mode to select programs.
In Phrase Trainer mode, a phrase from an audio device (ie., CD or DAT) connected to the AUX IN
jack or a guitar connected to the INPUT jack can be recorded and looped (played back repeatedly).
You can practice by playing along with the repeating loop. As you can fix the pitch and slow down
the playback speed, the phrase trainer mode is convenient for learning or practicing difficult
phrases.
When you enter this mode, the MODULATION, PEDAL, and AMBIENCE effect blocks will automatically be
turned off. In this mode it is not possible to switch programs or effect channels.

Effect channels of the AX1500G
The AX1500G provides an effect channel switch that lets you switch between two effect channels
(A and B) within each program.
Each channel consists of a drive amp effect and a cabinet effect (see the diagram below).

CABINET

This allows you to switch between rhythm and lead sounds within a single program as if you
were changing the channel of a guitar amp, or to differentiate between sounds intended for direct
output to a mixer using the cabinet effect or for output to your guitar amp.

2. Playing the AX1500G
Example connections
The power must be off when you make connections.
Unintentional operation may damage your speakers, or
cause malfunctions.
1. Connect your cables from the OUTPUT jacks of the
AX1500G to your guitar amp or mixer etc.
If you are using a mono connection, connect the L/
MONO jack. In order to take full advantage of the
AX1500G’s sound, we recommend that you use
stereo connections.
2. If you wish to use headphones, plug them into the
PHONE jack.
The output from the OUTPUT jacks will be turned off
when headphones are plugged in.
3. Connect your guitar to the INPUT jack.
4. If you wish to use the AUX IN jack, connect an
external audio device to it. Use the controls of the
connected device to adjust the volume.
5. Connect the included AC adapter to the DC 9V jack,
and plug the AC adapter into an AC outlet. When
you plug it in, the power will come on automatically, and the name display will indicate the
program name.
Wrap the AC adapter cable around the cable hook. When
removing the cable from the hook, be careful not to pull
the cable with excessive force.
6. When you have finished making connections, turn
on the power of your guitar amp or mixer etc. Play
your guitar, and check whether connections have
been made correctly. Adjust the master level of the
AX1500G and the gain or fader controls of your
guitar amp or mixer to set an appropriate volume
level.

selected when the power was turned off.
Adjusting the master level
The MASTER/VALUE display will show the master
level immediately after the power is turned on, a
program is selected, and after the EXIT switch is
pressed.
When the master level is shown, you can use the
MASTER/VALUE switches (▲, ▼) to adjust the master
level.
Selecting a program
You can select from 48 preset programs and 48 user
programs.
User and preset programs are each organized into 16
banks, with three programs in each bank. The currently selected bank is shown by the bank
number display, and the program is
shown by the program LEDs. To switch
between user and preset programs,
simultaneously press MASTER/VALUE
switch (▲) and cursor switch (®). When a
user program is selected, a decimal point
“.” located at the lower right of the bank
number display will light.
To select a program in the same bank
Press a program switch 1—3 to select the desired
program. The program LED of the selected program
will light, and the name display will indicate the
program name.
To select a program from a different bank
Press the bank switch to select the desired bank. (The
bank number display will blink.) The banks will cycle
in the order 0, 1, 2, ...9, A, b, C, d, E, F, 0, 1, 2...
• Each time you press the bank switch, the bank
number display will increase by one.
• Each time you simultaneously press the bank
switch and program switch 3, the bank number
display will decrease by one.
When the desired bank number appears, press
program switch 1,2 or 3 to select the desired program.
(The bank number display will change from blinking
to lit.)
Checking the effect blocks used by a program
Not every program uses all of the effect blocks. When
you select a program, the LED of each effect block that
are used will light. The LEDs of effect blocks that are
unused will be dark.
