Introduction
Welcome!
Thank you for adding the T ONEW ORKS AX3A Modeling Signal Processor to your r ig. Whether you’re playing live or in the studio, or practicing
with headphones, the AX3A will give you countless hours of great sounds!
To ensure a long and trouble-free relationship with your AX3A, please
read this manual carefully, and use it as directed. When you’ve finished
reading this manual, please keep it for future reference.
Main features
❑ Detailed and powerful modeling sounds delivered by Korg’s
modeling technology.
What is
is Korg’s proprietary sound modeling technology which digitally simulates a wide range of factors that affect the sound, including the
sound-producing mechanism of acoustic, electric, and electronic instruments, the body and cabinet resonances of these sounds, their
acoustical sound field, the electrical and electronic response of the
mics and speakers that propagate, these sounds, and even electronic circuit components such as vacuum tubes and transistors.
❑ 43 different modeling effect variations are built-in, and you can use
up to seven different effects simultaneously (including noise reduction and notch filter).
❑ All parameters of the effects in the five effect categories (pre-effect,
mic & body, tone, modulation, delay/reverb) can be fully edited.
❑ Use these modeling effects to create your own sounds and store
them in internal memory as one of 40 user programs. In addition, 40
more programs are provided as presets for immediate use.
❑ The built-in notch filter lets you eliminate unwanted acoustic feed-
back.

AX3A Owner’s manual
❑ Connect an optional Korg EXP-2 foot controller or XVP-10 expres-
sion/volume pedal, and use it as a wah pedal or volume pedal.
❑ The delay sound is preserved when you switch between programs
that have the same delay type and TIME parameter [P1] setting. Similarly, the reverberation is preserved when switching between programs that have the same reverb type.
❑ A built-in auto chromatic tuner lets you tune while bypassed or muted.

Selecting effects and adjusting the main parameters
[PRE FX], [MIC&BODY],[MOD], [DELAY/REV ]
To select the effect you want to use in each of the categories [PRE FX],
[MIC&BODY], [MOD], and [DELAY/REV], set the function selector to the
appropriate position and use the [▲][▼] buttons.
The program/value display will indicate a value of F0–F9, and the LED
at the top of the Program Down switch will light to indicate that the program/value display is showing the effect type .If the function select knob
is set to [TONE], the P1-P4 values are displayed.
The effect list printed on the panel tells you the effect type that is selected.
You can turn the value knob to adjust the “main” parameter for the selected effect. At this time the prog ram/value displa y will indicate the value
of the parameter, and the LED at the top of the Program Up switch will
light to indicate that the program/value display is showing the par ameter
value.
To switch [TONE] on/off, press both of the [▲][▼] switches simultaneously.
The parameter type or value is shown if this is switched on, and an “ ”
indication if this is off.
■ Quick guide
When you select an effect, the AX3A automatically sets the parameters
of that effect to their most effective values. In other words, you can create great sounds just by choosing an effect for each of the categories
PRE FX, MIC&BODY, MOD, and DELAY/REV, without having to make
detailed parameter settings.
By adjusting the main parameters, you can tweak your sound to what
you have in mind.
Selecting and adjusting sub-parameters and [TONE] parameters
[PRE FX-PARAM], [TONE], [MOD-PARAM], [DELAY/REV-PARAM]
Here's how to edit the sub-parameters for the effect selected in [PRE
FX], [MOD], and [DELAY/REV], as well as the parameters for [TONE].
When you press the [▲] or [▼] buttons, the program/value display will
indicate a value of P1–P4, and the LED at the top of the Program Down
switch will light to indicate that the program/value display is sho wing the
parameter type.
For the sub-parameters that correspond to P1–P4, refer to p.44 “Appendices”.
Now you can use the value knob to adjust each sub-parameter to your
taste.
At this time, the program/value display indicates the v alue of the parameter, and the LED at the top of the Program Up switch will light to indicate that the program/value display is showing the parameter value.
If an effect other than [TONE] is turned off, the program/value display
will indicate “
that category. If you want to edit the parameters of that effect, simulta-
neously press both [▲] and [▼] buttons to turn the effect on.
■ Quick guide
When you want to make adjustments to the sound of the effect you've
selected, you should start by adjusting the main parameter, and then
adjust the P1 sub-parameter. In most cases, adjusting these two par ameters will give you the sound you want. ([TONE] is an exception to this.)
[LEVEL/NR/NOTCH]
Select this position when you want to select or adjust the program le vel,
noise reduction, or notch filter. Then press the [▲] or [▼] buttons to
” when you turn the function select knob to [PARAM] for
AX3A Owner’s manual
cycle the display through LE (prog ram level), nr (NR sensitivity), and nF
(notch filter). Use the value knob to adjust each parameter.
LE: Use the value knob to adjust the program level (0–10). A setting of
7.0 is the standard value. Some effect settings may cause clipping.
If this occurs, lower the program level.
nr: Adjust the noise reduction sensitivity (0–10) so that you don’t hear
noise (hiss) when you’re not playing your guitar.
Depending on the guitar you’re using, notes may be cut off if you
raise the noise reduction value excessively. Adjust this so notes ring
out naturally.
nF: This adjusts the notch filter (oF, 1-63) that reduces acoustic feed-
back. Turn the knob to set the cutoff frequency at which acoustic
feedback will be reduced. The notch filter will be off if you turn the
knob all the way to the left. Turn the knob toward the right to move
the cutoff frequency from low to high, and find the point at which the
acoustic feedback is occurring.
Effect/parameter type and parameter value display
When you press the Program Down switch in Edit mode, the program/
value display will indicate the effect type or parameter type (F0–F9, P1–
P4). When y ou press the Program Up switch, the program/value display
will indicate the parameter value. This gives you a convenient way to
check the current settings.
Saving a program (Write mode)
Here’s how to save (write) a sound that you’ve created.
If you switch to a different program in Program mode or turn off the power
without writing your settings into memory, the changes you made will be lost.
1.
Set the function selector to [WRITE].
2.
Press the [▲(WRITE)] button. The program number will blink.

3.
Use the value knob or the Program Up/Down switches to select the
program in which you want to save your settings.
4.
Press the [▲(WRITE)] button once again. The progr am will be saved,
and the program/value display will indicate “
The newly saved program will overwrite (i.e., replace) the existing
settings, so that the previous program in that location will be lost.
If you decide not to save the new progr am, press the [CANCEL] b utton to cancel the operation.
” briefly.
Muting the AX3A
Simultaneously press and hold down the Program Up and Program Down
switches for about one second and the output will be muted. At this time,
the program/value display will indicate “
When bypassed or muted, the Auto Chromatic Tuner will be active. To
cancel the bypass or mute function, press the Program Up or Program
Down switch (this will not change the program).
In the bypassed state, the value knob acts as the master volume.
”.
Checking the values saved in a program (Original Value)
The Original Value LED in the program/
value display lets you check the parameter
values of a saved program.
When you use the knob or switches to
modify the value of a parameter, the Original Value LED will light when that value
matches the value that’s already been sav ed
in the program (i.e., the original value).
In Program mode, the Original Value LED will light if the values of all
parameters match the values that are saved in the program.
Bypass and Mute
Bypass (which turns off all effects including noise reduction) and Mute
(which mutes the AX3As output) are convenient functions for use while
you’re adjusting your guitar amp, tuning during a live performance, or
switching guitars. Here’s how to use Bypass or Mute.
Bypassing the AX3A
Simultaneously press the Program Up and Program Down switches; all
effects will be bypassed. At this time, the program/v alue displa y will indicate “

Tuner
The AX3A has a built-in Auto Chromatic Tuner.
You can calibrate the reference pitch (the note “A”) of the tuner in a
range of A438 Hz–A445 Hz.
Tuning procedure
1.
The Auto Chromatic Tuner will be activated when the AX3A is bypassed or muted.
If you want to tune silently , such as during a live perf ormance, simply
mute the AX3A.
2.
Play a note on your guitar and the program/value display will indicate the name of the closest note.
Note names are indicated as follows.

guitar is farther from the correct pitch.
When in tune, both the Program Up and Down LEDs will light.
AX3A Owner’s manual
Never turn off the power while reloading.
Adjusting the tuner calibration
When you turn on the power, the built-in tuner is set to a reference pitch
of A 440 Hz (concert pitch). You can calibrate this reference pitch in a
range of 438 Hz–445 Hz. You can use the [▲]/[▼] buttons to calibrate
this in the range of 438 Hz–445 Hz. When doing so, the program/value
display will indicate a value of 38–45.
When you turn off the power, the calibration adjustment you made will
be discarded and the AX3A will automatically be set to 440 Hz.
Restoring the factory preset programs
