Features

●

Amazing delay times, even allowing long delays of up to 5.2 seconds (*1).
Even in HOLD mode, there is plenty of room for loop play and sound on sound.

●

Includes the world’s first “warp” function, which allows you to use the pedal to shift
from the most popular, standard delays to some out-of-this-world spaces, with fantas­tic delays.

●

This 2-in/2-out full stereo delay puts out a delay sound with a big, solid sound.

●

Provides stereo effects like panning and “direct + effect.”

●

The delay time can be set in real time by pressing the pedal to input the tempo.

(*1) Some of the effects can be set to a maximum of 2.6 seconds when used in stereo.

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.

* As soon as you connect the AC adaptor, the unit

is turned on.

* If there are batteries 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).

* Use only the specified AC adaptor (PSA-Series).

2. CHECK Indicator

This is a combination indicator, which indi­cates whether the effect is on or off, indicates
the various functions (p. 12–15), and func­tions as the battery check indicator.

Panel Description

The indicator lights when an effect is ON.

* If this indicator goes dim or no longer lights

while an effect is ON, or when the functions are
indicated, the battery is near exhaustion and
should be replaced immediately. For instructions
on changing the batteries, refer to “Changing
the Battery” (p. 19).

* The CHECK indicator shows whether the effect

is on or off, and indicates the different functions.
It does not indicate whether the power to the
device is on or not.

3. OUTPUT-A (MONO) Jack
OUTPUT-B Jack

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

* The unit’s functions differ according to how it is

connected. Refer to “Setting the Output
Method” (p. 16).

4. INPUT-A (MONO) Jack
INPUT-B Jack

These jacks accept input signals (coming
from a guitar, some other musical instru­ment, or another effects unit).

* The unit’s functions differ according to how it is

connected. Refer to “Setting the Output
Method” (p. 16).

* When running the unit on battery power, the

INPUT-A (MONO) and INPUT-B jacks double
as power switches. Power to the unit is turned
on when you plug into the INPUT-A (MONO)
or INPUT-B jack; the power is turned off when
the cable is unplugged. Be sure to disconnect
any cord plugged into the INPUT-A (MONO)
or INPUT-B jack when not using this effects
device. When the AC adaptor is used, the power
remains on at all times, and this function is
disabled.

* For instructions on changing the battery, refer

to “Changing the Battery” (p. 19).

7. E.LEVEL (effect level) Knob

This adjusts the volume of the effect sound.
Turn the knob to the right (clockwise) to in­crease the effect sound. When set to MAX,
the effect is played at the same volume as the
direct sound.

* Only the effect sound is output when the E.LEVEL

knob is set to MAX while in REVERSE mode.
