Instructions
Thank you for purchasing the BOSS AW-2 Auto Wah
effect pedal. To take full advantage of this device,
be sure to read these instructions carefully.
•The AW-2 can create a variety of automatic wah-
wah(auto wah) effects using the SENS (Sensitivity)
control and the Modulation function.
•By using the picking wah and the modulation wah
at the same time, different wah effects can be
produced at picking and decay.
•By setting the basic frequency with the Manual
Control, a unique wah effect of narrow variable
band can be produced.

■ PANEL DESCRIPTIONS
OAC ADAPTOR JACK
Connect an AC adaptor (BOSS PSA-120, 220 or
240) to this jack.
♦ An AC adaptor provides a stable, dependable
supply of power.
♦ Be sure to use a BOSS PSA-120, 220 or 240,
depending on the voltage system in your coun¬
try. Using any other type of AC adaptor may
cause malfunctions.
©CHECK INDICATOR
This LED lights when the effect is turned on.
♦ The Check indicator also serves as a battery
check. When the LED becomes dim, replace the
battery.
©Modulation RATE Knob
This knob controls the rate of the modulation
effect. Clockwise rotation increases the rate and
counterclockwise rotation decreases it.
♦ When the Modulation DEPTH knob is at MIN(0),
the Modulation RATE knob does not function.
OModulation DEPTH Knob
This knob controls the sweep width (variable
range) of the modulation effect. Clockwise rota¬
tion makes the range wider. At MIN(0), no
modulation effect is produced.
♦ To control the wah effect with your playing inten¬
sity only, set the Modulation DEPTH Knob to
MIN(0).
©OUTPUT JACK
Connect an amplifier or other effect to this jack.
©PEDAL SWITCH
Pressing the pedal turns the effect on and off.
©THUMB SCREW
Loosen the screw to open the pedal for battery
replacement.
For a detailed explanation of battery replacement,
refer to "BATTERY REPLACEMENT".
©SENS Control Knob
This knob adjusts the sensitivity of the wah effect.
Rotating the knob clockwise allows you to obtain
a wah effect even with soft playing. Rotating the
knob counterclockwise produces wah effects only
with harder playing.
♦ The intensity of the wah effect will be affected
not only the volume, but also by the type of
pickup on your instrument. Adjust the SENS
control knob so that an appropriate sensitivity is
obtained for your guitar and playing style.
♦ When the SENS control knob is at MIN (0), no
wah effect will be produced even by increasing
picking strength.
©MANUAL Knob
This knob controls the basic frequency (where the
wah effect starts to work). Rotating the knob
clockwise will increase the frequency, while rotat¬
ing it counterclockwise will decrease it.
♦ The maximum frequency of the wah effect
(obtained by using the SENS control knob) is
fixed. Setting the MANUAL knob to HI (. ^)will
decrease the width of the sweep (variable
range).
©INPUT JACK
Connect an electronic/electric musical instrument
(such as a guitar)to this jack.
♦ Connecting a plug to this jack will automatically
switch the unit on. Be sure to disconnect the
plug from this jack when the unit is not being
used.
r-H CONNECTIONS
Connect the AC Adaptor Jack
AC Adaptor:
BOSS PSA-120,
220 or 240(:optional)
♦ Connecting an instrument to the Input Jack will
automatically switch the unit on.
♦ Before connecting or disconnecting any instru¬
ment, make sure that the volume of the ampli¬
fier is turned down.
♦ Using a high-output instrument with the AW-2
may cause sound distortion. If this happens,
turn down the volume on the instrument or use
a limiter to decrease the volume.

■ OPERATION
[To control the Wah effect with the Modulation Function]
1'Set the control knobs as shown in the diagram
to below. Turn on the effect by pressing the
pedal. (Make sure that the Check Indicator
lights.)
2'Adjust the rate of the modulation effect with the
RATE Knob. Clockwise rotation will increase
the rate, while counterclockwise rotation will
decrease it.
* If you wish
— ■ OPERATION
[To control the Wah effect with playing strength]
1 Set the control knobs as shown in the diagram
to below. Turn on the effect by pressing the
pedal. (Make sure that the Check Indicator
lights. )
*When the Modulation DEPTH knob is set to
MIN(Q), no modulation effect is produced.
The Modulation RATE knob will therefore not
function either.
[|)Adjust the sensitivity of the wah effect using the
SENS control knob. Rotating the knob will
allow you to obtain a wah effect even with soft
playing. Rotating the knob counterclockwise
will allow you to obtain the effect only with
stronger playing.

■ SAMPLE SETTINGS
[Picking Wah by Sens Control]
Wah effect can be created by changing picking
strength. Adjust the position of the Sens Control
Knob depending on the guitar you use and the
playing style.
[Manual+Sens Wah]
Wah effect starts working at the frequency set
with the Manual Knob.
* When the Manual Knob is set to the HI ( 0 )
[Modulation Wah]
This is a wah effect created by using the Modula¬
tion function. The same effect obtained with the
Pedal Wah will be automatically created.
[Manual + Sens+Modulation Wah]
Wah effect starts working at the frequency set
with the Manual Knob. When the input sound is
decreasing, modulation effect is added.
■ BATTERY REPLACEMENT
0 Loo sen the thumb screw on the pedal
to open it.
(2) T a k e out the battery from the battery
housing and disconnect the battery
snap.
(3) C o n n e c t a new battery to the battery
snap,then replace the battery in to the
battery housing.
* Make sure that the polarity of the
battery is correct.
(4) P u s h the coil spring into the spring
base on the rear of the pedal,then
close the pedal.
* Make sure that the snap cord is not
caught in the pedal or coil spring.
©Insert the thumb screw into the guide
bush hole and firmly tighten the
screw.
Use one 9-volt battery
[Manual + Modulation Wah 1]
Wah effect takes on modulation at the low fre¬
quency set with the Manual Knob.
[ManualsModulation Wah 2]
Wah effect takes on modulation at the high fre¬
quency set with the Manual Knob.
[Sens+Modulation Wah]
Picking wah is created, then modulation wah is
added when the input sound is decreasing.
[Filter Effect]
This creates filter effect similar to that obtained
by stopping the Pedal operation (Pedal Wah).
You can change the frequency of the filter using
the Manual Knob.
■ IMPORTANT NOTES
•Do not subject the unit to temperature
extremes (eg. direct sunlight in an
enclosed vehicle). Avoid using or
storing the unit in dusty or humid
areas or areas that are subject to high
vibration levels.
• Remove the battery whenever the unit
is not going to be used for an
extended period of time.
• When operating solely on a battery,
the unit's indicator becomes dim
when the battery is depleted. Replace
the battery immediately.
• If there is a battery in the unit while
an AC adaptor is being used, normal
operation will continue should the line
voltage be interrupted (power black¬
out) or the power cord become dis¬
connected .
• Should a malfunction occur (or if you
suspect there is a problem) dis¬
continue use immediately. Contact
qualified service personnel as soon as
possible.
• OUT:9VDC 200mA
