Expression Pedal - HEADRUSH Pedalboard User Manual

Expression Pedal

The expression pedal can control two parameters (in Classic Mode) or two sets of parameters (in Advanced
Mode). Use the toe switch to switch between them—Expression Pedal A or B.
To activate the toe switch, move the "toe end" of the expression pedal so it touches the pedalboard, and then
press down. The expression pedal status LED will indicate A or B.
The column of four boxes represents the expression pedal settings. You can
assign one or more continuously adjustable parameters (ones with a range of
values) to the expression pedal.
To set the expression pedal mode, tap the button above Range in the
upper-right corner to select Classic or Advanced.
Classic: You can assign one parameter to each expressional pedal (A and
B). Using the toe switch will select the other expression pedal and deactivate
(bypass) the current expression pedal's parameter. For instance, if you
assign a wah pedal to Expression Pedal A and a volume pedal to Expression
Pedal B, only one of them will be active at any time; when you are controlling
the wah pedal, the volume pedal will be bypassed, and vice versa.
Advanced: You can assign up to four parameters to each expression pedal
(A and B). Moving the pedal will adjust all of its assigned parameters
simultaneously. Using the toe switch will select the other expression pedal
and leave the current pedal's parameters active and at their maximum values.
Important: You cannot edit any parameters assigned to the expression pedal
in Classic Mode (they will show a lock icon and be greyed out in other
screens to indicate this). You can edit any parameters assigned to the
expression pedal in Advanced Mode (they will show a pedal icon in other
screens to indicate this).
To assign a parameter to the expression pedal:
1. If the Assign button is not on, tap it.
2. Tap a box under the Assign button.  indicates an empty box.
3. In the list that appears, tap the model with the parameter you
want to assign.
4. In the list that appears, tap the parameter you want to assign.
Tap Unassigned  to unassign that box.
To swap two assignments (while in Advanced Mode), tap and
drag one of them over the other, and then release it.
To set the range of an assigned parameter:
1. If the Range button is not on, tap it.
2. Tap a value under the Range button.
3. Turn the encoder to set the desired value as a percentage of the parameter's entire range.
Press the encoder or tap elsewhere to confirm the value.
