9 MODIFIERS
Below you will find a basic step-by-step tutorial on setting up the modifier for a wah pedal.
For this example, let’s assume:
A Wah block is in your preset.
You have an Expression pedal ready (see
p. 12
for how to connect pedals directly to the Axe-Fx III).
Here are the steps:
1. On the Grid,
NAV
to your Wah block and press
EDIT
to show its menu.
2. Turn to the Config page of the Wah block’s Edit menu.
3. Notice the yellow Modifier dot symbol beneath the on-screen Wah Control parameter.
4.
NAV
to select that parameter (or just give its knob a twiddle). It will be highlighted when selected.
5. Press
ENTER
or the MODIFIER Push-knob to show the Modifier menu.
6. On the Source page, change the SOURCE to your pedal. Depending on how your pedal is connected this
might be “Pedal 1” (the on-board expression jack of the Axe-Fx III), or it might be one of the “External
Controllers” (
p. 106
), or it might be one of the “FC” pedal options.
7. Test! The Wah should work when you move the pedal. You’ll also see the dot move on the graph. If it
doesn’t work, check your source or make sure the pedal is properly connected and calibrated.
8. Save the preset by pressing

MODIFIER TIPS AND TRICKS
The same source can be assigned to multiple modifiers at the same time. For example, one pedal
might adjust Chorus Rate and Chorus Depth at the same time — even in different ways.
The modifiers for a given block will be shared across all of its channels.
Modifiers use a very small amount of CPU power while you use them.
Test any presets which seem close to the edge.
All of the Internal Controllers (Tempo, LFOs, ADSRs, etc.) are part of a Controllers block. This block
has four channels, so you can have up to four different sets of Controller values in one preset.
The Axe-Fx III has a dedicated Bypass parameter in every block that can be bypassed, and this
parameter allows you to assign a modifier. Bypass Mode is not used as it was on the Axe-Fx II.
The Wah in this example is controlled by an expression pedal. An expression pedal can be used to control other
parameters like whammy control, rotary rate, delay feedback, and many, many more.
There are also many different sources we could use instead of a pedal. Try an LFO for a modulating auto-wah, or
an Envelope Follower for some funky Mu-Tron action. And MIDI opens up a world of controller options.
