modeling technology.
❑ 58 types of modeling effect variation are built in, and you can use up
to six different effects (including noise reduction) and volume pedal
simultaneously.
❑ You can edit all of the parameters for each effect in the four effect
❑ 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. (p.54
“Preset program chart”)
❑ The AX5B provides an expression pedal that lets you control not
only wah and volume but also many effect parameters, giving you
enormous possibilities for live performance.
❑ The Quick Assign function lets you easily assign a parameter to the
expression pedal with one touch.
❑ The delay sound is preserved when you switch between programs
that have the same delay type and TIME parameter [P1] setting. Similarly, the re v erb is preserved when s witching between programs that
have the same reverb type.
❑ A built-in auto chromatic tuner lets you tune while bypassed or muted.

Press the Program Up or Program Down switch to select a program.
The program/value displa y shows the number of the prog ram you selected.
Expression pedal
Each program specifies the expression pedal’s control target (volume,
wah, or an effect parameter). When you move the pedal up or down
while performing, the sound of the program will change accordingly.
By pressing the pedal setting switch, you can change the target controlled by the expression pedal. Each time you press the s witch, the control target will change in the order of VOLUME ➜ WAH ➜ FX PARAM ➜
VOLUME ..., and the LED for the target being controlled will light or blink.
VOLUME (LED=orange):
WAH (LED=red):
FX PARAM (LED=green):
For a program that assigns the expression pedal’ s control target as WAH or
FX PARAM, advancing the pedal forward will turn off the effect being controlled by the pedal, and the expression pedal LED will change from lit to
blinking. Once again advance the pedal forward, and the effect being controlled will turn on; the expression pedal LED will change from blinking to lit.
If the expression pedal’s control target is VOLUME, the position of the
volume pedal will control the volume of the selected program.
In the case of W AH or FX PARAM, the sound of the program will not change
until you actually operate the expression pedal after switching programs.
The pedal will operate as a volume pedal.
The pedal will operate as a wah pedal. In this
case, [PRE FX] will be assigned as a pedal wah.

■ Quick guide
When you select an effect, the AX5B 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, DRIVE/AMP, 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.
Here’s how to edit the sub-parameters of the eff ect you’v e selected f or each
of the [PRE FX], [DRIVE/AMP], [MOD], and [DELAY/REV] categories.
When you press the [▲] or [▼] buttons, the prog ram/value displa y will indicate
a value of P1–P4, and the LED in the upper part of the program down pedal
will light (or blink) to indicate that the parameter type is being displayed.
For the sub-parameters that correspond to P1–P4, refer to p.51 “Parameter List”.
Now you can use the value dial to edit the sound by adjusting the various sub-parameters. At this time, the prog ram/v alue display will indicate
the parameter value, and the LED in the upper part of the program up
pedal will light to indicate that the parameter value is being displayed.
If the effect is turned off, the program/value display will indicate “ ”
when you set the function selector to a [PARAM] position for that category. If you want to edit the parameters of that effect, simultaneously
press both the [▲] and [▼] buttons to turn the effect on.
■ Quick guide
To select an effect and edit it to your taste, you should first adjust the main
parameters, and then adjust sub-parameter P1. In most cases, you’ll be
able to get the sound you want by adjusting these two parameters.
[LEVEL/NR/CAB/PEDAL]
Set the function selector to this position when you want to adjust the
program level, noise reduction, or cabinet modeling. Then press the [s]
or [t] buttons to cycle the display through “ ”(program level), “ ”
(NR sensitivity), “ ”(cabinet), and “ ”, “ ”(Expression pedal
target range). Use the value knob to adjust each parameter.
: Use the value knob to adjust the program level (0.0–10). A setting
of 5.0 is the standard value. Some effect settings may cause clipping. If this occurs, lower the program level.
: Adjust the noise reduction sensitivity (0.0–10) so that you don’t hear
noise (hiss) when you’re not playing your bass.
AX5B Owner’s manual
Depending on the bass you’re using, notes may be cut off if you raise the
noise reduction value excessively. Adjust this so notes ring out naturally .
: Select the type (C0–C9) of cabinet modeling.
You can’t edit the cabinet model if the drive/amp model is off. In this
case, the LED will indicate “
Cabinet modeling is associated with the drive/amp model. It works
only if the drive/amp model is turned on. When y ou change the drive/
amp model type, the most suitable cabinet model is selected automatically.

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, d0–
d5, A0–A9, P1–P4). When you 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.
Expression pedal settings
Make the program/value display sho w the effect par ameter (F0–F9, d0–
d5, A0–A9, P1–P4). Make sure that the LED of the progr am up pedal or
program down pedal is blinking, and then hold down the pedal setting
switch for about one second.
You can’t use the expression pedal to control a parameter for which the
program up pedal or program down pedal does not blink.
The program/value displa y will briefly indicate “ ”(Complete), and you’ll
be able to use the expression pedal to control the effect parameter.

If the expression pedal’s control target is FX PARAM, changing the category of the effect controlled by the pedal will reset the pedal control
target to the most useful parameter of the selected effect. (p.51 “Parameter List”)
If you set the expression pedal’s control target to FX P ARAM, the corresponding effect will automatically be turned On. If, in this state, you operate the pedal or press the pedal setting switch once to select V OLUME
without editing the setting, the effect will automatically be turned Off again.
However, if you did operate the pedal or edit the setting, the effect will
remain On even if you press the pedal setting switch once again to select VOLUME as the target.
If the expression pedal’s control target is W AH, y ou can turn the function
