Expression Pedals:
What Are They For?
Expression pedals are used to manually control certain
parameters such as volume. Instead of having your
entire signal go through 10 meters of cable or more
using a regular volume pedal, you can connect an
expression pedal and use it to adjust the G-System’s
volume parameter.
But expression pedals can do much more. How about
letting an expression pedal control the pitch as a
Whammy pedal, or the level of Delay repeats, or the
speed of a Tremolo? There are countless possibilities.
For each preset, you can define which parameters the
expression pedals should control. This means that in
each preset, the pedals can serve different functions.
You may, however, prefer a setup where e.g. the
expression pedal controlling the volume always controls
the volume. That is why you can set the pedal
assignment as a global parameter.
If we look at the G-System with the Control Board and
GFX01 separated, you will see that there are two
Expression Pedal Inputs on the GFX01:
… and two Expression Pedal Inputs on the Control
Board:
These connectors are “clones” – meaning that you can
control two different parameters per preset, but you can
actually hook up two expression pedals for each function.
For example, you can place two pedals onstage right
next to the Control Board and another two on the
“catwalk” for full control when you solo.
All four Expression Pedal Inputs can be
individually calibrated.
The Vol Pedal Input is per default assigned to the G-
Systems’ In Gain parameter and connecting an
expression pedal to that connector will automatically
allow this pedal to control that parameter.
However, as previously described it is entirely up to you
what to control with the expression pedals.

Connecting Pedals
Depending on the type of expression pedal used, the
pedal should be connected using either a regular mono
1/4" jack-to-jack cable or a stereo 1/4" jack-to-jack cable.

Stereo
If you are not sure, you may have to try both types.
The G-System measures the signal on your expression
pedals output connector. Therefore only one cable
should be used per expression pedal.
Important Note
• True expression pedals can be used to control
all types of parameters in G-System.
• Regular volume pedals should only be used to
control volume parameters. Using a regular
volume pedal to control e.g. whammy or wah
effects, will most likely give an unsatisfying
result.
