Thanks for purchasing the Bubbler Chorus — a
modern take on a timeless modulation effect. The
Bubbler is a classic sounding bucket
brigade-based chorus pedal with modern
flexibility. Switch back and forth between Slow
and Fast speeds using the footswitch or control
the rate of modulation with your playing
dynamics via the Sensitivity control. The Bubbler
Chorus can add depth and interesting textures to
any rig.
BUBBLER CHORUS
DESIGNED IN CALIFORNIA, U.S.A.

Rate 1
While the Slow speed is selected, the Rate 1 control adjusts the speed
of the modulation.
Rate 1 LED
This LED is illuminated when the Slow Speed is engaged. Rate 1 and
Rate 2 are active when this LED is on.
Depth 1
While the Slow speed is selected, the Depth 1 control adjusts the
intensity of the chorus.
Center LED (LED between Depth 1 and Rate 2)
This LED blinks in time with the rate of the Bubbler.
Rate 2
While the Fast speed is selected, the Rate 1 control adjusts the speed of
the modulation.
Rate 2 LED
This LED is illuminated when the Fast Speed is engaged. Rate 1 and
Rate 2 are active when this LED is on.
Depth 2
While the Fast speed is selected, the Depth 1 control adjusts the
intensity of the chorus.
Level
The Level control adjusts the amount of the chorused signal added to
your instrument’s dry signal.
Wave Type Switch
This switch allows you to toggle between sine and triangle shaped
modulation.
Sensitivity
When the Slow mode is engaged, the Sensitivity control adjusts the
threshold for the Bubbler’s dynamically controlled rate. As the Sensitivity
is turned clockwise, the Bubbler can automatically switch from Slow to
Fast settings with the changes in your instrument’s volume—softer
playing will keep the Bubbler set to your Slow settings; louder playing
will send the Bubbler ramping up to your Fast settings. Turn the
Sensitivity control fully counter-clockwise to disable this feature.

Sensitivity LED
This LED will illuminate when your instrument’s signal passes the
threshold set with the Sensitivity control to ramp the Bubbler’s chorusing
speed from the Slow settings to the Fast settings.
Jewel Indicator
The Jewel Indicator shows when the chorus effect is active.
Bypass Footswitch
This footswitch is used to bypass the effect.
Slow/Fast Footswitch
This footswitch is used to toggle between the Slow and Fast chorus
speeds. The Slow controls are Rate 1 and Depth 1; the Fast controls
are Rate 2 and Depth 2.
Input Jack
This is a high-impedance input suitable for electric guitar, bass, acoustic
guitars with pickup systems, keyboards and other instruments.
Left/Mono Output Jack
This is a low-impedance output jack that connects to the amp or to the
next effect pedal in a mono signal chain.
Right Output Jack
This is a low-impedance output jack that connects to the amp or to the
next effect pedal in a stereo signal chain.
DC Power Connector
This is a standard center-negative 9VDC jack for use with appropriate
power supplies.
LED Kill Switch
This switch extinguishes the LEDs that illuminate the knobs.
