Precautions
• Avoid using the AG-Stomp in the following locations to prevent possible damage:
• In direct sunlight or next to heating equipment.
• In extremely cold or hot locations.
• Locations exposed to high humidity or excessive dust.
• Locations subject to strong shocks or vibration.
• Before making any connections, make sure that the power is switched OFF on the AG-Stomp
and any external devices.
• To protect speakers from possible damage, always set the OUTPUT knob to “0” before switching
the power ON/OFF.
• When connecting a speaker to this unit, make sure that the power is switched OFF first.
• Do not apply excessive force to the switches, knobs and controls.
• The AG-Stomp is a precision device. Handle it with care and avoid dropping or jarring it.
• For safety, always remove the power adaptor from the AC wall outlet if there is any danger of
lightning striking in your area.
• Keep the AG-Stomp away from neon signs or fluorescent lighting to prevent noise pickup.
• To prevent damage and possibly electrical shock, never open the case and tamper with the
internal circuitry.
• Never use benzene, thinner or other volatile liquids for cleaning, as these chemicals may cause
damage or discoloration to the finish. Always use a dry, soft cloth to wipe off dust and dirt.

balanced). Connect these jacks to the input jacks
on a power amp and speaker system, guitar amplifier, mixer, etc.
A commercially available PA type TRS phone cable
can be used to send a TRS balanced audio signal
from the AG-Stomp. Also, the supplied TRS-XLR
converter cables connected to these jacks deliver a
balanced audio signal to the XLR jacks on a mixer,
etc. (→ page 10)
* Use the L/MONO jack when connecting to a monaural de-
vice.
#5 INPUT Jack
#6 Input MUTE Switch
This is the AG-Stomp’s input jack. Connect a guitar

The supplied TRS phone cable can be used to deliver power to an electric-acoustic guitar’s built-in preamplifier from the AG-Stomp. (→ page 12)
When pressed, the Input MUTE Switch ( ) cuts
the signal from the INPUT jack to prevent noise,
etc. from entering the circuit. Use this switch when
connecting or disconnecting the guitar’s cable.
9
Connections
Before making any connections to any of the AG-Stomp’s INPUT and/or OUTPUT jacks,
make sure that the power on the AG-Stomp and all other devices is turned OFF to prevent
electrical shock or damage to the devices.
■ Connecting the Power
Use the supplied power adaptor (AC-10) to operate the AG-Stomp.
1. Make sure the AG-Stomp’s Power Switch (STAND-BY) is in the OFF
position ( ).
2. Connect the power adaptor’s plug to the AC IN jack on the AG-Stomp.
3. Connect the power adaptor to an electric outlet.
Only use the supplied AC-10 power adaptor to power the unit.
The use of any other power adaptor may cause damage, overheating or fire, which can be very dangerous.
Make sure you use the proper AC voltage as indicated on the
power adaptor.
Never use the supplied power adaptor AC-10 with any other
device.
■ Connecting a Mixer or Amplifier
1. Use the supplied TRS-XLR converter cable to convert the AG-Stomp’s outputs (balanced TRS) to balanced XLR outputs.
2. Use a commercially available PA type TRS phone cable, to connect the AG-Stomp’s output jack to the
balanced inputs of a mixer, power amplifier, etc.
3. When a monaural phone cable is used, connections will be unbalanced.
