Owner’s Manual
Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (supplied on a separate sheet).
After reading, keep the document(s) where it will be available for immediate reference.
AC Adaptor
(PSA series; sold separately)
Electric Guitar
English
LEVEL knob
This knob adjusts the volume of the eect sound. Set this knob so that there will
be no dierence in volume between the eect and straight sounds.
* No sound will be heard when this knob is rotated completely
counterclockwise.
7 The MT-2 is compact yet creates powerful eect pedal which, through the use of high-level gain circuits, creates heavy distortion and sustain eects.
7 The MT-2 includes a three-band equalizer, Low, Middle and High. The middle band EQ is adopted for parametric type.
OUTPUT jack
Connect an amplier or other eect unit to this jack.
Guitar Amplier
DC IN jack
Accepts connection of an AC Adaptor (PSA series; sold separately). By using an AC Adaptor, you can play
without being concerned about how much battery power you have left.
* We recommend that you keep batteries installed in the unit even though you’ll be powering it with
the AC adaptor. That way, you’ll be able to continue a performance even if the cord of the AC adaptor
gets accidentally disconnected from the unit.
* Use only the specied AC adaptor (PSA-series).
* If the AC adaptor is connected while power is on, the power supply is drawn
from the AC adaptor.
CHECK indicator
This indicator shows whether an eect is ON/OFF, and doubles as the Battery Check indicator.
The indicator lights when an eect is ON.
* If this indicator goes dim or no longer lights while an eect is ON, the battery is near
exhaustion and should be replaced immediately.
EQUALIZER HIGH knob
This knob controls the tone of the eect sound at higher frequencies.
Rotating the knob clockwise boosts the higher frequencies, while rotating it
counterclockwise cuts the higher frequencies. Higher frequencies have a variable
range of ±15 dB.
Pedal Switch
This switch turns the eects ON/OFF.
Thumbscrew
When this screw is loosened, the pedal will open, allowing you to change the
battery.
* For instructions on changing the battery, refer to “Changing the Battery.”

Precautions When Connecting
5
To prevent malfunction and equipment failure, always turn
down the volume, and turn o all the units before making any
connections.
5
Once the connections have been completed, turn on power to
your various devices in the order specied. By turning on devices
in the wrong order, you risk causing malfunction and/or damage
to speakers and other devices.
When powering up: Turn on the power to your guitar amp last.
When powering down: Turn o the power to your guitar amp rst.
5
Before turning the unit on/o, always be sure to turn the volume
down. Even with the volume turned down, you might hear some
sound when switching the unit on/o. However, this is normal and
does not indicate a malfunction.
Use of Battery
5
A battery was installed in the unit before it left the factory. The life
of this battery may be limited, however, since its primary purpose
was to enable testing.
5
If you handle batteries improperly, you risk explosion and uid
leakage. Make sure that you carefully observe all of the items
related to batteries that are listed in “USING THE UNIT SAFELY” and
“IMPORTANT NOTES” (supplied on a separate sheet).
5
When operating on battery power only, the unit’s indicator will
become dim when battery power gets too low. Replace the
battery as soon as possible.
5
Batteries should always be installed or replaced before connecting
any other devices. This way, you can prevent malfunction and
damage.
Changing the Battery
1. Hold down the pedal and loosen
the thumbscrew ,
then open the pedal upward.
* The pedal can be opened without
detaching the thumbscrew completely.
2. Remove the old battery from
the battery housing , and
remove the battery snap
connected to it.
3. Connect the battery snap to the new battery, and place
the battery inside the battery housing.
* Be sure to carefully observe the battery’s polarity (+ versus -).
4. Slip the coil spring onto the spring base on the
back of the pedal, and then close the pedal.
* Carefully avoid getting the battery snap cord caught in the
pedal, coil spring, and battery housing.
5. Insert the thumbscrew into the guide bush hole and
tighten it securely.
9 V Battery
EQUALIZER MIDDLE knob
This knob boosts or cuts the frequency you set with the EQUALIZER MID FREQ
knob. Rotating the knob clockwise boosts the level of the middle frequencies,
while rotating it counterclockwise cuts the level of the middle frequencies.
EQUALIZER MID FREQ knob
This knob sets the frequency of the middle range (200 Hz to 5 kHz). Rotating the
knob clockwise raises the frequency. Rotating it counterclockwise lowers the
frequency.
* When the EQUALIZER MID FREQ knob is set to the center position, the
EQUALIZER MID FREQ knob does not aect the sound.
DIST knob
This knob controls the intensity of the distortion eect. Rotating the knob
clockwise increases the distortion level.
* If you set this knob too high, the noise will increase and oscillation may
occur.
EQUALIZER LOW knob
This knob controls the tone of the eect sound at lower frequencies.
Rotating the knob clockwise boosts the lower frequencies, while rotating it
counterclockwise cuts the lower frequencies. The lower frequencies have a
variable range of ±15 dB.
INPUT jack
This jack accepts input signals (coming from a guitar, some other musical
instrument, or another eects unit).
* The INPUT jack doubles as the power switch.
Power to the unit is turned on when you plug
into the INPUT jack; the power is turned o
when the cable is unplugged. To prevent
unnecessary battery consumption, be sure to
disconnect the plug from the INPUT jack when
not using the eects unit.

necessary connections, set
the knobs as shown in the
illustration.

lights.
3. Adjust the level of distortion
using the DIST knob.
Rotating the knob clockwise
increases the distortion level
while rotating it counterclockwise
decreases it.
* If this knob is set too high, the
noise will increase and oscillation
may occur.
4. Adjust the tone of the middle
range with the EQUALIZER
MIDDLE knob.
Rotating the knob clockwise boosts
the frequency while rotating it
counterclockwise cuts it.
5. Set the middle frequency (to be boosted or cut) with
the EQUALIZER MID FREQ knob.
* When the EQUALIZER MIDDLE knob is set to the center position,
moving the EQUALIZER MID FREQ konb does not aect the sound.
6. Adjust the tone of the high
range with the EQUALIZER
HIGH knob.
Rotating the knob clockwise boosts
the higher frequencies while
rotating it counterclockwise cut
them.
7. Adjust the tone of the low range with the EQUALIZER
LOW knob.
Rotating the knob clockwise boosts the lower frequencies while
rotating it counterclockwise cut them.
8. Using the LEVEL knob, adjust
the volume of the eect
sound so that there will be
no dierence in volume
between the eect and
straight sounds.
