IMPORTANT NOTES
In addition to the items listed under “USING THE UNIT SAFELY” on page 2, please read and observe the following:
5
Power Supply: Use of Batteries
• Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
• The use of an AC adaptor is recommended as the unit’s
power consumption is relatively high. Should you pre-
fer to use batteries, please use the alkaline type.
• When installing or replacing batteries, always turn off
the power on this unit and disconnect any other
devices you may have connected. This way, you can
prevent malfunction and/or damage to speakers or
other devices.
• Batteries are supplied with the unit. The life of these
batteries may be limited, however, since their primary
purpose was to enable testing.
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
Placement
• Using the unit near power amplifiers (or other equip-
ment containing large power transformers) may induce
hum. To alleviate the problem, change the orientation
of this unit; or move it farther away from the source of
interference.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
Maintenance
• For everyday cleaning wipe the unit with a soft, dry
cloth or one that has been slightly dampened with
water. To remove stubborn dirt, use a cloth impregnat-
ed with a mild, non-abrasive detergent. Afterwards, be
sure to wipe the unit thoroughly with a soft, dry cloth.
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
Additional Precautions
• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its
jacks and connectors. Rough handling can lead to mal-
functions.
• When connecting/disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
• To avoid disturbing your neighbors, try to keep the
unit’s volume at reasonable levels (especially when it is
late at night).
• When you need to transport the unit, package it in the
box (including padding) that it came in, if possible.
Otherwise, you will need to use equivalent packaging
materials.

Main Features
A go-anywhere, floor-type effects proces-
sor for electric acoustic guitars, designed
especially for live performances
• Equipped with two pedals (chorus and anti-
feedback auto)
• Low-profile, rugged steel body
Chorus and reverb tuned exclusively
for electric acoustic guitars
• Uses a stereo band-splitting chorus (2 x 2 cho-
rus) to apply effects separately to the bass
and treble bands
• A newly developed, built-in reverb
• The same level of quality as the full-featured
AD-5
An acoustic guitar-amp simulator you
can hook up and use with a guitar amp
• The AD-3 has an on-board acoustic guitar
amp simulator approaches the original sound
of an acoustic guitar, even with a guitar amp
Bottom and top control designed
exclusively for electric acoustic guitars
• The AD-3 has on-board bottom and top con-
trol for special filters that work differently for
boost and cutoff. This makes for a natural
acoustic sound.
Double anti-feedback reduces acoustic
feedback
• Along with the anti-feedback that sets the fre-
quency with a control knob, the AD-3 has a
built-in automatic anti-feedback function that
automatically detects the frequency by oper-
ating a pedal.
• You can use the two anti-feedback functions
at the same time.
“Anti-feedback” is a feature that reduces
acoustic feedback (howling) between the gui-
tar and amp.
Balance output
• The AD-3’s output is balanced, so you can
connect it directly to PA systems.
“Balanced output” is a system that reduces
noise when using stereo cables and so on to
send musical signals to a PA system or
another balanced device.
Dual Power Supply
• In addition to running the AD-3 off batteries
(six AA cells), you can use the AC adaptor.
This means you can use batteries for an on-
stage performance or the AC adaptor when in
your room.

When the batteries are depleted, the power indica-
tor grows dark. If this happens, replace with new
batteries.
When replacing the batteries, use six AA
batteries. Also, do not mix new and old bat-
teries or batteries of different types. Doing so
may cause fluid to leak from the batteries.
Make sure the “+” and “-” ends of the bat-
teries are oriented correctly.
Battery life may vary according to battery
type.
Expected battery life under continuous use:
Alkaline: Approx. 17 hours
Carbon: Approx. 9 hours
These figures will vary depending on the
actual conditions of use.

NOTE
Using an AC Adaptor
The BOSS PSA Series AC adaptor (sold separately)
can be used to run the AD-3 from a household elec-
trical outlet.
fig.PSA
Use only a dedicated AC adaptor (BOSS
PSA Series). Never try to use another AC
adaptor, because doing so may result in
incorrect operation or breakdown.
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).
To prevent the inadvertent disruption of
power to your unit (should the plug be pulled
out accidentally), and to avoid applying
undue stress to the AC adaptor jack, anchor
the power cord using the cord hook, as shown
in the illustration.

If you’re using a guitar amp, connect the OUTPUT
R jack to the guitar amp and set the OUTPUT
SELECT switch to G.AMP.
If you’re using stereo output and connecting the
AD-3 to an audio amp, a mixer, a multi-track
recorder, or the like, set the OUTPUT SELECT
switch to LINE.
To prevent malfunction and/or damage to
speakers or other devices, always turn down
the volume, and turn off the power on all
devices before making any connections.
Turn on the power on all connected equip-
ment before you turn up the volume on your
amplifier.
The AD-3 supports balanced output. For balanced
output, use a commercially available stereo stan-
dard cord or a stereo (standard) ↔Canon conver-
sion cord.

Turning the Power On
10
Once the connections have been completed (p. 9),
turn on power to your various devices in the order
specified. By turning on devices in the wrong
order, you risk causing malfunction and/or dam-
age to speakers and other devices.
AD-3 →Output Equipment
(Guitar Amp or Other Device)
1. Switch on the power for the AD-3.
fig.3b
The power indicator lights up and the power
comes on.
2. Turn on the output equipment.
This unit is equipped with a protection cir-
cuit. A brief interval (a few seconds) after
power-up is required before the unit will
operate normally. The peak indicator blinks
for a few seconds, then you can use the AD-3
for playing.
When running off batteries, the AD-3 won’t
switch on unless there’s something plugged
into the INPUT jack. This helps prevent run-
ning down the batteries. Be careful, because if
you unplug the equipment plugged into the
INPUT jack, the power switches off.
Turning the Power Off
Power down in the reverse order: first the output
equipment, then the AD-3.
Output Equipment
(Guitar Amp or Other Device) →AD-3
1. Turn off the output equipment.
2. Switch off the power for the AD-3.
