Controls
Footswitch
Click the footswitch to engage or bypass the pedal. Press + hold the footswitch down while the pedal
is bypassed to bank to Red LED (ALT) Mode for more presets.
Control Input / ALT Button
This small button located at the top of the pedal is used to enable or disable external control. It also
is used to control the ALT parameters on the surface of the pedal. Press + hold the ALT knob while
turning any of the control knobs to access their alternate parameters (see next page for ALT
Controls).
Engage/Bypass LED
The Engage/Bypass LED indicates whether the effect is bypassed or engaged. In ALT Mode (presets
4-6), the LED becomes red when the pedal is engaged.
Gain Reduction
By default, the Engage/Bypass LED also shows gain reduction by changing from green to red
whenever compression is being applied to the input signal. This feature can be turned off in the
Hardware Options section of the Neuro App and Desktop Editor.
