Using the AG-Stomp
First, connect your guitar to the AG-Stomp and try to get some sound.
■ Connecting the Guitar
Before making any connections, make sure the AG-Stomp’s power is off, set the AG-Stomp’s OUTPUT
knob to “0” and the +9V SUPPLY switch to “OFF”. Then connect the INPUT jack on the rear panel to the
guitar’s output jack with any commercially available guitar cable (monaural ↔ monaural).
OFF (
)
Never connect the guitar to the AG-Stomp with the supplied TRS phone cable when the Guitar Power Supply
function described below is not used. If the TRS phone cable is used and the +9V SUPPLY switch is switched
“ON”, it may result in damage since a total of 18V will be supplied to the electric-acoustic guitar’s built-in preamplifier. Also, if the +9V SUPPLY switch is set to “OFF”, the electric-acoustic’s built-in pre-amplifier may function abnormally.
● Guitar Power Supply
Before supplying power to your guitar, make sure
that the guitar’s pre-amplifier battery has been replaced with the dummy battery supplied with the
AG-Stomp. Leaving the 006P 9V battery in place will
result in the guitar’s electronics receiving 18V of
power, causing damage.
[Setting]
1. Replace the electric/acoustic guitar’s built-in pre-amplifier battery with the dummy battery supplied with the
AG-Stomp.
The AG-Stomp is capable of supplying power to your electric-acoustic guitar’s built-in pre-amplifier via the supplied
TRS phone cable. Power is supplied to the electric-acoustic
guitar when the AG-Stomp’s power is switched ON.
This function is possible as long as your electric-acoustic
guitar meets the following conditions:
3. Use the supplied TRS phone cable to connect the AGStomp’s INPUT jack to the output jack on your electric/
acoustic guitar.
• The guitar uses a monaural output.
• The guitar uses a 006P 9V battery to supply power
to the guitar’s built-in pre-amplifier.
• The power to the guitar’s built-in pre-amplifier is
switched ON/OFF by connecting/disconnecting the
cable at the guitar’s jack.
• The guitar’s built-in electronics consume 10mA of
power, or less.
* Do not connect effectors, etc., between the AG-Stomp’s INPUT jack and the electric-acoustic guitar’s OUTPUT jack.
Power will not be supplied to the electric-acoustic guitar’s
built-in pre-amplifier if the AG-Stomp and the electric-acoustic
guitar are not directly connected.
Replace the electricacoustic guitar’s preamplifier battery with the
dummy battery.
Dummy Battery
(supplied)
2. Before making any connections, turn off the AG-Stomp’s
power and make sure its OUTPUT knob is set to “0”,
then set the +9V SUPPLY switch to “ON”.
* When the AG-Stomp’s power is ON, make sure that the MUTE
switch on the AG-Stomp is held down when connecting/disconnecting the cable.
Set the +9V SUPPLY
switch to the “ON”
position.
TRS Phone Cable (supplied)

Using the AG-Stomp
■ Produce Sound
■ Editing Settings
1. After confirming that the OUTPUT knob is set to
“0”, press the Power Switch (STAND-BY) ON
( ).
The panel knob and button functions can be used
to create your own original tone.
Switching the Power Switch ON when the OUTPUT
knob is turned up may result in damage to devices
such as the amplifier, speaker, headphones, etc.,
or cause unexpected accidents like damage to
your hearing due to high volume settings.
2. “U01” will appear in the display.
The characters (Memory Area: U (user), Bank
Number: 0, Patch Number:1) indicate the currently selected patch.
When a patch number is shown in the display,
this condition is known as the Play Mode. When
in the Play Mode, patches can be selected and
the knobs and buttons can be used to edit settings.
● Changing Pre-amp Settings
Since the AG-Stomp’s knob positions do not always
represent the tone that is currently being produced,
the knob must be “aligned” with the value set in
memory before changes can be made to that value.
For this reason, please follow the rules described
below when rotating the knobs.
• If the [UP] lamp flashes when a knob is rotated,
rotate the knob to the right (toward 10). If the
[DOWN] lamp flashes, rotate the knob to the left
(toward 0).
At this time, the patch’s data value (the value set
in the patch for the knob you are turning) will
flash in the display.
* As long as the value is flashing in the display, the display
and tone will not change even though the knob is being
rotated.
For now, try using this patch to produce some
sound.
3. Play a chord on the guitar and rotate the OUTPUT knob to the right to adjust the volume.
* If clipping due to the input signal overloading the AG-Stomp’s
circuit occurs, the BANK Switch Lamp will light.
If this is the case, reduce the volume on the guitar, or adjust
the AG-Stomp’s VOLUME, individual TONE control knobs
or individual Effect knobs. Also, if feedback occurs, please
refer to the “Feedback Reduction” section on page 16.
• Continue rotating the knob, when the knob
reaches the position corresponding to the patch’s
data value, the display as well as the [UP]/
[DOWN] lamps will stop flashing. After this, the
tone will change according to the knob’s position.
* After you stop moving the knob, the value will be displayed
for approximately two more seconds, then return to the normal display.
* Even if only one value is changed, the [MANUAL] lamp
will flash to indicate that data in the patch has been
changed.
Also, when all settings (except for the OUTPUT knob) are
changed, the [MANUAL] lamp will light.
• Once the knob is in an editable condition (in
which the patch data’s value can be changed),
rotating the knob will result in the value shown in
the display changing in regards to the knob’s
position causing a relative change in tone.
13
Using the AG-Stomp
The previously described rules apply to all knobs
except the OUTPUT knob.
The MIC TYPE SELECT switch also functions in
the same manner. When the knob is rotated, the
Mic Simulator type that is set in the patch data
will flash in the display. After rotating the knob
to the position of the Mic Simulator type indicated in the display, select the Mic Simulator type
you want to use.
The OUTPUT knob and VOLUME knob
Either knob can be used to change the volume however, the VOLUME knob setting is stored in the patch
data while the OUTPUT knob’s setting is not. Use
the VOLUME knob to set the volume of each patch
and use the OUTPUT knob to control the AGstomp’s output volume.
● Set the Tone Control’s Center Frequency
The BASS, MIDDLE, TREBLE and PRESENCE
tone controls each have a variable center frequency.
[Procedure]
1. Press the [SHIFT] button so that its lamp flashes
(enter the SHIFT mode).
2. To adjust the Center Frequency, rotate the Tone
Control of the related frequency range you want
to set. Turn the knob to the left (counter-clockwise) to lower the center frequency, or turn the
knob to the right (clockwise) to raise the center
frequency.

Using the AG-Stomp
● Setting the Mic Simulator
The Mic Simulator is a specially designed circuit that adds to an electric/acoustic guitar, the special characteristics created when miking an acoustic guitar. It adds the airiness, which is found when a microphone is
placed in front of the guitar’s sound hole. The Mic Simulator is useful when your guitar is connected directly
to a mixer or recorder via a line, or when listened to through a pair of headphones for practice, etc.
The AG-Stomp provides the eight different Mic Simulator settings described below. The Mic Simulator creates a
stereo image by simulating two microphones positioned in front of the guitar but “aimed” at dif ferent angles
toward the guitar. Use the MIC TYPE Select Switch to try out some of the different microphone simulation types.
The BLEND knob is used to adjust the volume balance between the signal after it has passed through the Mic
Simulator (MIC tone) and the signal before it has passed through the Mic Simulator (DIRECT tone). Rotate the
knob fully to the left to hear only the DIRECT tone. Rotate the knob fully to the right to hear only the MIC tone.
Also, pressing the [SHIFT] button to enter the SHIFT mode (the SHIFT lamp flashes) lets you use the
BLEND (stereo) knob to adjust spaciousness of the sound produced by the Mic Simulator’s two microphones. Press the [SHIFT] button again to exit the SHIFT mode and the lamp will turn off.
* In the SHIFT mode, if a knob is not rotated after five seconds, the mode will be exited automatically.

Description of the Simulation
* Mic Simulator settings are stored in patch data (MIC TYPE Select Switch Settings).
* When the Volume and Tone controls are set to high, the signal may clip inside of the AG-Stomp. In this case, decrease the guitar’s
volume, or adjust the AG-Stomp’s VOLUME, individual Tone Controls or individual Effect knobs. Also, if feedback occurs, please
use the Feedback Reduction Function described on page 16.
15
Using the AG-Stomp
● Feedback Reduction
The AG-Stomp is equipped with a Feedback Reduction Function to prevent feedback.
Feedback is caused when a certain frequency or
frequencies of the amplified sound causes the guitar to resonate thereby being re-amplified until a
steady howl or whistle is heard.
The AG-Stomp prevents feedback from occurring
by means of a notch filter, which is used to cut the
problem frequency. The AG-Stomp provides a total
of five notch filters (1-5) that can be applied and
operate simultaneously.
[Procedure]
The AG-Stomp provides two ways to set Feedback
Reduction.
• AUTO Setting
When feedback occurs, press the BANK switch.
The AG-Stomp will automatically identify the
problem frequency and apply an available notch
filter.
* The DEPTH is set to its maximum value (knob 10: -20dB)
in the AUTO setting.
* When feedback occurs with chords, etc., the AUTO setting
might not provide adequate performance. In this case, use
the MANUAL setting as described in the next section.
• MANUAL Setting
Press one of the [FEEDBACK REDUCTION]
buttons 1-5 (its lamp will flash). Use the FREQ
knob to select the frequency that needs to be
cut, then use the DEPTH knob to adjust the
amount of reduction needed.
Signal Level
Amount of reduction
Frequency
that needs
to be cut
Frequency
16
After adjustments have been made, press the
same button to set the setting (the lamp will light
and the filter will be active).
To deactivate (lamp OFF) an active filter (lamp
ON), press and hold the button of the filter you
want to deactivate until “OFF” appears in the
display.
* Refer to the “EFFECT FUNCTIONS and PARAMETERS”
section (page 21) for more information on settings for each
of the Feedback Reduction’s knobs.
If feedback is continuously occurring at a
high volume level, it may cause damage
to equipment. Please use caution.
Depending upon Utility Mode settings, Feedback Reduction settings are either included
with patch data (PrG) or, kept separate of
patch data so that the same Feedback Reduction settings/parameters will remain active (GLb) even though a different patch is
selected. (→ page 27)
Also, if the “GLb” (global) setting is used in
the Utility Mode, Feedback Reduction settings will be stored as global data when patch
data is stored so, the settings will be erased
if the power is turned off before the settings
are stored.
When another patch is selected, any settings that were changed will be returned
to their original condition. If you want to
keep the changes you made to those settings, use the Store Operation described
on page 19.
Using the AG-Stomp
■ Selecting Patches
The AG-Stomp holds a total of 60 patch programs
(patch) in its internal memory. The 60 patches are
divided into two areas, ten banks and three patches.
• AREA
There are two areas, the USER AREA and the
PRESET AREA. Data in the USER AREA (30
patches) can be freely rewritten using the
STORE operation. Data in the PRESET AREA
(30 patches) can be edited but the contents can
not be rewritten to PRESET AREA memory.
When a USER AREA patch is selected, a “U”
will appear in the display’s hundred’s digit (U01U93).
When a PRESET AREA patch is selected, a “P”
will appear in the display’s hundred’s digit (P01P93).
* When the AG-Stomp is shipped, both the PRESET AREA
and USER AREA contain the same patch data. (Refer to
the supplemental [Patch List]).
• BANK
The 30 patches in each area are divided into ten
banks (0-9).
● Use the [UP]/[DOWN] buttons on the
panel.
• Each time the [UP] button is pressed, the next
greater patch number is selected.
U01 → U02 → U03 → U11 → U12 →
U13.....U91 → U92 → U93 → P01 →
P02.....P93 → U01 (returns to the top)...
Each time the [DOWN] button is pressed, the
next lesser patch number is selected.
• Holding the [UP] button continuously increases
the bank number by one.
U01 → U11 → U21 → U31.....U91 →
P01 → P11.....P91 → U01 (returns to
the top)...
Holding the [DOWN] button continuously decreases the bank number by one.
• Simultaneously press the [UP] and [DOWN] button switches between the USER AREA and
PRESET AREA.
U01 ↔ P01

3. Create a Program Change Table*.
→ page 24 [Create a Program Change Table]
* This operation assigns patch numbers to corresponding
program change numbers that are received from an external device. For example, when the program change number “1” is received, the AG-Stomp’s patch number “U13”
is recalled.
* The default for Program Change Number: Patch Number
is
1: U01, 2: U02, ... 60: P93, 61: U01, ... 120: P93, ...128: U22.
4. When program change data is transmitted from
an external MIDI device and received by the AGStomp, the corresponding patch in the Program
Change Table you created will be selected.
* Refer to the Owner’s Manual of your external MIDI device, etc., for information on how to transmit program
change data.
