HYDRA STEREO REVERB & TREMOLO
EXPRESSION PEDAL INPUT
You must use a TRS (stereo) expression pedal with the
HYDRA. If you use a mono cable (or volume pedal), the
HYDRA will not power on.
When a TRS (stereo) expression pedal is inserted, the
expression pedal defaults to controlling the RATE control of
the TREMOLO.
Note: Plugging a mono cable into the TRS EXP. PEDAL jack
will allow the control of the Tap Tempo.
CLEAR ALL EXPRESSION SETTINGS
To clear ALL expression pedal settings, enter Expression
Pedal Mode by holding the COLOR knob for 2 seconds. Once
in Expression Pedal Mode, hold TREMOLO footswitch for 2
seconds to clear ALL expression pedal settings and reset
them to default. Once finished, exit Expression Pedal Mode
by holding the COLOR knob for 2 seconds.
FACTORY RESET
Hold down the COLOR knob + TREMOLO + REVERB
footswitches while applying power to the unit.
All LEDs will flash in succession and all controls, secondary
controls, modes, memory and presets will
return to default settings.
You will see all of the lights on the HYDRA cycle, indicating
that the Factory Reset is complete.
Note: When making these adjustments, it helps to place the
HYDRA on a flat surface, such as a pedalboard or a table top.
