Serves for connection of the optional foot switch (FS01) or expression pedal (FP01/FP02).

Selecting a Patch

To try out the various effects of the G1/G1X, we recommend that you simply play your instrument while switching patches.

Turn power on

When using the G1/G1X on batteries, plug a shielded cable with mono phone plug into the [INPUT] jack on the rear panel of the G1/G1X. When using the G1/G1X with the AC adapter, plug the adapter into the outlet and plug the cable from the adapter into the [DC IN] jack on the G1/G1X. Turn the guitar amplifier on and adjust the volume to a suitable position.

Adjust the master level

To adjust the master level in play mode, you can use the [VALUE] knob.
When you turn the [VALUE] knob, the master level setting is shown for a time on the display.
The master level setting range is 0 98, 1.0. It will be reset to 80 when the unit is turned off and then on again.
Set the G1/G1X to play mode
If the Module selector is set to a position other than "PLAY", set it to "PLAY".
The currently selected bank and patch number are shown on the display.
When using headphones, this knob adjusts the listening volume.

Bank name Patch number

Immediately after turning the G1/G1X on, the unit will be in play mode, even if the Module selector is set to a position other than "PLAY".

Select a patch

To switch the patch, press one of the [W]/[Q] foot switches.
Pressing the [W] foot switch calls up the next lower patch, and pressing the [Q] foot switch calls up the next higher patch. Repeatedly pressing one foot switch cycles through patches in the order A0 A9. d0 d09. A0, or the reverse order.
Directly selecting a bank
To select the banks A - d, 0 - 3 directly, use the [BANK UPTAP] key.
Each push of the key switches to the next higher bank.
With the G1, using the foot switch (FS01) to switch banks is also possible ( p. 16).

Using the Tuner

The G1/G1X incorporates an auto-chromatic tuner. To use the tuner function, the built-in effects must be bypassed (temporarily turned off) or muted (original sound and effect sound turned off).
Adjusting the reference pitch of the tuner
If required, you can fine-adjust the reference pitch of the G1/G1X tuner.

Turn the [VALUE] knob.

Switch to bypass or mute
Setting the G1/G1X to the bypass state
In play mode or rhythm mode ( p. 10), press both [W]/[Q] foot switches together briefly and release.
When you turn the [VALUE] knob in the bypass/mute condition, the current reference pitch is shown for a time on the display. The default setting is 40 (center A = 440 Hz).
While the reference pitch is shown, turn the [VALUE] knob to adjust the value in the range from 35 - 45 (center A = 435 to 445 Hz).
Setting the G1/G1X to the mute state

In play mode or rhythm mode ( p. 10), press both [W]/[Q] foot switches together and hold for at least 1 second.
The bypass or mute condition cannot be activated when the unit is in edit mode.
Patch change at bypass/mute
When you press both [Q]/[W] foot switches together while playing your instrument, the sound may change momentarily just before the bypass/mute condition is activated. This is because the G1/G1X switches to the next higher or lower patch when one of the foot switches is pressed slightly earlier. (When you cancel the bypass/mute condition, the original patch number will be active again.) This behavior is not a defect. It is due to the very high speed at which the G1/G1X responds to patch switching. To prevent the sound change caused by the above condition, do not produce sound with your instrument until the bypass/mute condition is fully established.
Shortly after you release the [VALUE] knob, the display indication will revert to the previous condition.
When you turn the G1/G1X off and on again, the reference pitch setting will be reset to 40 (center A = 440 Hz).

Return to play mode

Press one of the [W]/[Q] foot switches.

Tune your instrument

Play the open string to tune, and adjust the pitch.
The right side of the display shows a symbol that indicates by how much the tuning is off.

The left side of the display shows the note which is closest to the current pitch.
Using the Rhythm Function

Adjust the rhythm volume

The G1/G1X has a built-in rhythm function that plays realistic drum sounds in various patterns. The rhythm function is available in play mode and in rhythm mode. This section describes how to use the function in rhythm mode.
To adjust the rhythm volume, turn the [VALUE] knob.
When you turn the [VALUE] knob, the current setting (0 30) is shown for a time on the display.

When you return to play mode and have made any change to the patch, the dot (.) will be shown in the bottom right of the display. If you select another patch in this condition, the changes you have made in edit mode will be lost unless you store the patch first. To retain the changes, store the patch as described on page 14.

Storing/Copying Patches

An edited patch can be stored in a bank of the user area (A d). It is also possible to store an existing patch in another location to create a copy.
To cancel the store process
To cancel the store process, operate the [VALUE] knob before pressing the [STORE] key again in step.
In play mode or edit mode, press the [STORE] key.
The bank and patch number are shown on the display as a flashing indication.
Patches of banks in the preset area (0 3) are read-only. No patches can be stored or copied into these locations. If you press the [STORE] key while a patch from the preset area is selected, the patch "A0" (bank A, patch number 0) will be selected automatically as default store/copy target.
Press the [STORE] key once more
When the store/copy process is completed, the G1/G1X returns to the previous mode, with the target patch being selected.
Specify the store/copy target patch number
To specify the store/copy target patch number, use the [W]/[Q] foot switches.

Select the store/copy target bank
To select the store/copy target bank, use the [BANK UPTAP] key.
Only a bank of the user area (A - d) can be selected as store/copy target bank. During the store/copy process, the foot switch (FS01) cannot be used to change banks.
Using a Foot Switch or Pedal
Changing the Way Patches Are Called Up
In normal operation, changing a patch in play mode of the G1/G1X will be active immediately. This means that the sound changes straight away when you make the selection. In some cases, such as when the new patch is at a memory location not adjacent to the current one, this method may not be ideal, because the sound will change in various ways as you switch through the patches. In such a case, you may want to change the patch selection method to "pre-select". In this mode, you first select the patch to use next, and then perform an additional step to activate the patch. To change G1/G1X operation to pre-select, perform the following steps. Turn power to the G1/G1X on while holding down the [Q] foot switch. The indication "PrE-SElEct" scrolls on the display during startup.
more, the G1 detects the interval and automatically adjusts the tempo accordingly (tap tempo function).

Edit mode

Control target
DELAY module REVERB module
The foot switch has no effect. HINT
In the section "Effect Types and Parameters" (page 19 24), a pedal symbol indicates which effect type/parameter is controlled by the pedal. When a module has been selected as control target, but the effect type currently selected for that module does not have a pedal symbol, the expression pedal has no effect.
Using the expression pedal
With the G1, an expression pedal (FP01/FP02) can be connected to the [CONTROL IN] jack and used as a volume pedal or for adjusting a certain parameter of an effect type in real time. With the G1X, the built-in expression pedal can be used in the same way. The function of the expression pedal can be selected and stored individually for each patch.
In play mode, use the [W]/[Q] foot switches to specify the patch to use next. You can use the [BANK UPTAP] key or a foot switch (FS01) connected to the [CONTROL IN] jack to switch only the bank (The G1X does not support use of a foot switch.) The new bank or patch number specified by the above step flashes on the display. The sound does not change yet.
When you have specified the patch to use, press both [W]/[Q] foot switches together. The patch change is accepted, the display changes from flashing to permanently lit, and the sound changes.
Store the patch as required. The expression pedal setting is stored for that patch. Select this patch in play mode, and operate the expression pedal. The respective parameter changes when you operate the pedal (pushing the pedal down has the same effect as increasing the value of the parameter). In the bypass condition, the expression pedal always functions as volume pedal, regardless of the setting made in step 4.
