The EXP-1 Expression Pedal is a dual-mode foot controller that enables the user to control
master volume (“Volume” mode) and various amp and effect parameters (“Expression” mode).
Switch between Volume and Expression modes by stepping on the toe switch (top of the
pedal). Red and green LEDs indicate the mode in use. Volume mode—indicated by the green
LED—controls master volume or can be turned off. Expression mode—indicated by the red
LED—controls Rumble Studio 40/Stage 800 parameters such as wah frequencies, modulation effect rates, etc.
To set up the EXP-1, connect it to the footswitch jack on the back of the amp and turn the amp on. Press the
MENU utility button on the amp and use the ENCODER to scroll to and select the “FOOTSWITCH” menu option.
Then use the ENCODER to scroll to and select “EXP-1 (EXPRESSION)” from the menu shown (
see illustrations below
).
A prompt will appear to select “PRESET SETTINGS” or “GLOBAL SETTINGS” (
see illustration below
); use the EN-
CODER to select one. PRESET SETTINGS is used to assign the EXP-1 to a specific amp or effect
within a particular
preset
, in which a wide variety of parameters can be modified, depending on the amp or preset in use. GLOBAL
SETTINGS is used to configure parameters that will affect
all
presets. Both are described in more detail below.
PRESET SETTINGS
As noted above, PRESET SETTINGS is used to assign the EXP-1 to a specific amp or effect within a particular
preset. To do this, press the ENCODER on PRESET SETTINGS, and the middle SIGNAL PATH LAYER will show—
one at a time—the amp and effects in that preset to which the EXP-1 can be assigned. The user can scroll
through these by turning the ENCODER (
see illustration below
).
