W-2HM Heavy Metal Waza Craft
Product Information
The HM-2W is a guitar effects pedal that offers various sound
variations and tone adjustments. It can operate on a 9-volt battery
or a 9-volt AC adaptor (PSA series, sold separately). The pedal
features a CHECK indicator that shows the status of the effect and
the battery level. It has knobs for adjusting the tone frequency
ranges, a mode switch for selecting sound variations, a level knob
for adjusting the volume, and a pedal switch for turning the
effects on/off. The pedal can be connected to a guitar amplifier or
another effects unit using the OUTPUT jack.
Panel Descriptions
- DC IN jack: Used for connecting a 9-volt AC
adaptor (PSA series) to power the unit. - AC adaptor (PSA series): A separate AC adaptor
that can be used instead of the battery for power supply. - CHECK indicator: Indicates if an effect is
on/off and also serves as the battery check indicator. - [COLOR MIX H] knob: Adjusts the tone around
the 1 kHz frequency range. - [COLOR MIX L] knob: Adjusts the tone around
the 100 Hz frequency range. - Mode Switch: Switches between the standard
sound and a custom sound with enhanced aggression. - [LEVEL] knob: Adjusts the volume of the effect
sound. - OUTPUT jack: Used to connect the pedal to a
guitar amplifier or another effects unit. - Pedal switch: Turns the effects on/off.
- Thumbscrew: Loosening this screw allows the
pedal to open for battery replacement. - [DIST.] knob: Adjusts the gain and distortion
effect. - INPUT jack: Accepts input signals from a
guitar, other musical instruments, or effects units. It also
functions as the power switch.

HM-2W Owner’s Manual
English
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.
Panel Descriptions
DC IN jack
In addition to 9-volt battery operation, this unit can also operate on a 9-volt AC adaptor (PSA series; sold separately).
* Use only the specified AC adaptor (PSA series; sold separately), and connect it to an AC outlet of the correct voltage.
AC adaptor (PSA series; sold separately)
* If the AC adaptor is connected while a battery is installed, the power supply is drawn from the AC adaptor.
CHECK indicator
This indicator shows whether an effect is ON/OFF, and doubles as the Battery Check indicator.
The indicator lights when an effect is ON.
* The brightness of the CHECK indicator (LED) will dim as the battery lowers. Replace the battery when the LED is dim or does not light. For instructions, refer to “Changing the Battery.”
Adjusts the tone around the 1 kHz frequency range. Turn the knob clockwise to boost, and counterclockwise to cut.
[COLOR MIX L] knob
Adjusts the tone around the 100 Hz frequency range. Turn the knob clockwise to boost, and counterclockwise to cut.
Mode Switch
Switches the sound variation.
S (Standard) C (Custom)
Reproduces the original HM-2 sound by a newly crafted all analog circuit.
This gives you a custom sound that’s been tuned up to be even more aggressive.
This knob adjusts the volume of the effect sound. * No sound will be heard when this knob is rotated
completely counterclockwise.
OUTPUT jack
Use this 1/4″ output jack to connect to the input of your guitar amplifier or the input of additional effect unit.
Guitar Amplifier
Pedal switch
This switch turns the effects 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.”
Rotating the knob clockwise increases the gain and distortion effect.
* If you set this knob too high, the noise will increase and oscillation may occur.
INPUT jack
Electric guitar
This jack accepts input signals (coming from a guitar, some other musical instrument, or another effects 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 off when the cable is unplugged. To prevent unnecessary battery consumption, be sure to disconnect the plug from the INPUT jack when not using the effects unit.
Precautions When Connecting Changing the Battery
Main Specifications
· To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.
· Once everything is properly connected, be sure to follow the procedure below to turn on their power. If you turn on equipment in the wrong order, you risk causing malfunction or equipment failure.
When powering up: When powering down:
Turn on the power to your guitar amp last.
Turn off the power to your guitar amp first.
· Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.
· Do not use connection cables that contain a built-in resistor.
Use of Battery
· The life of the included battery may be limited as its primary purpose was for testing during assembly.
· If you handle batteries improperly, you risk explosion and fluid 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).
· 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.
· If the batteries run extremely low, the sound may distort, but this does not indicate a malfunction. If this occurs, please replace the batteries or use the AC adaptor (sold separately).
· Batteries should always be installed or replaced before connecting any other devices. This way, you can prevent malfunction and damage.
