Features

●

The BOSS CEB-3 is a chorus unit that is specifically designed for electric bass guitar.

●

The CEB-3 allows you to select the frequency band to which the chorus effect will ap­ply. That is, you can have the effect applied to the overall sound, or only a specific
frequency range if you wish.

Using the two channel outputs, deeper chorus effects can be created.

1. AC Adaptor Jack

Accepts connection of an AC Adaptor (op­tionally available BOSS PSA-Series). By
using an AC Adaptor, you can play with­out being concerned about how much bat­tery power you have left.

* Use only the specified AC adaptor (PSA-

Series), and make sure the line voltage at the

6

installation matches the input voltage
specified on the AC adaptor's body. Other
AC adaptors may use a different polarity, or
be designed for a different voltage, so their
use could result in damage, malfunction, or
electric shock.

* As soon as you connect the AC adaptor, the

unit is turned on.

* If there is battery in the unit while an AC

adaptor is being used, normal operation will
continue should the line voltage be interrupted
(power blackout or power cord disconnection).

2. CHECK Indicator

This indicator shows whether an effect is
ON/OFF, and also doubles as the Battery
Check indicator.
The indicator lights when an effect is ON.

* If this indicator goes dim or no longer lights

while an effect is ON, the battery is near
exhaustion and should be replaced immedi­ately. For instructions on changing the
batteries, refer to “Changing the Battery” (p.

11).

* The CHECK indicator shows whether the

effect is being applied or not, and is used to
indicate other effects. It does not indicate
whether the power to the device is on or not.

OUTPUT A (MONO)/ OUTPUT B Jack

The output jacks are used to connect the
unit to an amplifier or another effects unit.

* For monaural output, use Output jack A.

Both the dry and processed signals are
output.

* For stereo use:

Output A: Only the processed signal (pitch

Output B: Only the dry signal is output.
The CEB-3 adopts the “space synthesis sys-

tem” for stereo output. That is, the depth of the
effect varies depending on the distance be­tween speakers. Note that lowering a filter
control knob or effect level too much will shift
the sound image to the Output B position, and
therefore diminish the effect. Experiment with
different as you play the instrument

modulated sound) is output. The
dry (unprocessed) signal is not
output.
