Expression pedal

The target function (volume, effect parameter) of the expression pedal
is set for each program. By rocking the pedal up or down during
a performance, the tone and volume will be changed accordingly.
For programs where the target function of the expression pedal is
other than volume, the target function of the effect will turn off when
the pedal is pressed strongly and the expression pedal LED will
turn off. If the pedal is pressed strongly again, the effect of the target
function will turn on and the expression pedal LED will light up.
When volume is set as the target function of the expression pedal,
volume of the program will be set according to the current position
of the pedal. For target functions other than the volume, the tone
of the program cannot be changed until the expression pedal is
used after the program is switched.
HINT: Set the [AMP/DRIVE] LEVEL as the target function when the
volume is controlled by the expression pedal as it is controlled by
the volume pedal and when the program volume does not change
8
until the pedal is used after the program is switched.

Bypass and Mute

Bypass (which turns off all effects including noise reduction)
and Mute (which mutes the StompLabs output) are convenient
functions to use while you're adjusting your bass amp, tuning
during a live performance, or switching basses. Here's how to
use Bypass or Mute.
Bypassing the StompLab
Simultaneously press the Program UP and Program DOWN
pedals; all effects will be bypassed. At this time, the program/
value display will indicate " – – ".
Muting the StompLab
Simultaneously press and hold down the Program UP and Program
DOWN pedals 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 pedal (this will not change the program).
The StompLab has a built-in Auto Chromatic Tuner.
You can calibrate the reference pitch (the note "A") of the tuner
in a range of 438Hz–445Hz.
