INPUT jackConnect your guitar.
CTL4, 5/EXP2 jacks, CTL6, 7/EXP3 jacksYou can control various parameters by connecting an expression pedal (Roland EV-5: sold separately) or a footswitch (FS-5U, FS-6, FS-7: sold separately).
For details on the settings, refer to “Foot Switch and Expression Pedal Settings” (p. 12).
• Use only the specified expression pedal. By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit.
AMP CTL 1,2 jacksBy connecting this to the channel switching jack of your guitar amp, you can switch channels from the GT-1000. For details on the parameter, refer to the “GT-1000 Parameter Guide” (PDF file).
DC IN jackConnect the included AC adaptor here.* Place the AC adaptor so the side with the indicator (see illustration) faces upwards and the side with textual information faces downwards. The indicator will light when you plug the AC adaptor into an AC outlet.
MIDI IN/OUT jacks
Connect an external MIDI device here. (p. 10)
- To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.
- 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.
- To prevent the inadvertent disruption of power to your unit (should the plug be pulled out accidentally), and to avoid applying undue stress to the jack, anchor the power cord using the cord hook, as shown in the illustration.

1. Press the [EFFECT] button.
The edit screen (effect chain) appears.
2. Turn knob [6] to select the block that you want to edit.
The selected block is enclosed by a thick frame.
* By pressing knob [6] you can turn the selected effect on/off. Effects that are off are shown in gray. When the effect is turned on, it is shown in white.
3. Use knobs [1]-[5] to adjust the parameters that are shown below the screen.
Use the PAGE [][] buttons to switch between the parameters that you want to edit. The current page is indicated in the lower center of the screen.* To change a value in larger steps, turn a knob while pressing it.* The number of parameters and pages differs depending on theeffect.
Editing while viewing all parameters
From the edit screen, you can long-press knob [6] to see a list of all parameters of the selected block. You can edit the parameters from this list.
1. Turn knobs [1]-[6] to edit the value of the parameters shown in the screen.Use the PAGE [][] buttons to switch between lists of parameters.

Switching patches without interrupting the sound
The GT-1000 is equipped with a new type of high-speed patch switching system, allowing you to switch patches with minimal interruption of the sound. The fastest possible switching is automatically performed for each patch, and switching without interrupting the sound is also possible.
Tips for preventing interruptions in the sound
To prevent interruptions in the sound, observe the following points when you create the patches that are used before and after the switch.• Avoid changing the position of blocks within the chain.• Use multiple blocks when placing the effects (don’t change the TYPE within the same block).• Use parallel positioning, and switch the channel.
Example:Switching from a clean sound that uses chorus and deep delay, to a crunch sound that uses phaser and shallow delay.
The same chain is used for both patches, both before and after switching. The settings of the effect used before switching are placed in parallel with the settings used after switching.
Using STOMPBOX
Your preferred settings for each effect can be saved as a “STOMPBOX.” You can select these saved settings and use them to create your sound just as though you were connecting compact pedal effects. The STOMPBOX data is common to all patches; this means that all patches using the same STOMPBOX can be edited simultaneously.
1. Press the [EFFECT] button.2. Use the [6] knob to choose the effect you’re going to edit.3. Use the PAGE [] [] buttons to move to the last page.
4. Press the [5] knob.The STOMPBOX select window appears.

Looper
You can record up to 38 seconds (MONO) of a performance and play back the recorded section over and over. You can also layer additional performances with the recording as it plays back (overdubbing). This lets you create real-time backing performances on the fly.
Assigning Looper Functions to Switches
To use the looper, you must first assign the looper’s record, play, and overdub functions to the desired switches. Here we explain an example of how you can use the [CTL1]-[CTL3] switches of the GT1000 to operate the looper.
1. Select the patch with which you want to use the looper.2. Choose [MENU]→“CONTROL ASSIGN”→“CONTROL FUNCTION.”3. For “CTL 1″-”CTL 3,” set FUNCTION as follows.
| Parameter | Value | Explanation |
| CTL 1 | LOOPER | Starts recording. Each time you press the switch, operation alternates between playback and overdubbing. |
| CTL 2 | LOOPER STOP | Stops recording or playback. |
| CTL 3 | LOOPER CLEAR | Clears the recording. |
MEMO• With the factory settings, preset patches P50-1P50-5 and user patches U50-1-U50-5 are set as shown above.• You can also stop and clear using only the [CTL1] switch that is assigned to LOOPER. Press the switch twice to stop. Hold down the switch for two seconds or longer to clear the phrase.
RecordRecording will start immediately when you press the switch. At the point where you want to loop, press the pedal to switch to playback.
⇓
Loop PlaybackPlay back the loop.Pressing the switch will switch to overdubbing.
⇓⇑
OverdubRecord additional layers while playing back the loop.Press the switch to switch to playback.
⇓
Stop/ClearTo stop, press the switch to which STOP is assigned.To clear the phrase, press the switch to which CLEAR is assigned.
Loop Playback Level Setting
If you set the playback level at 100 (default value), the volume of the performance and that of the loop playback will be identical.If you set the playback level to a value lower than 100, the volume of the playback will be lower than that of the performance. As a result, the sound of the performance won’t get buried by the loop playback sound, even if you record a multiple number of times.
1. Press the [EFFECT] button.2. Turn knob [6] to select LOOPER.
3. Turn knob [1] to specify the “PLAY LEVEL” value.
Switch Color
| Color | Status |
| Red | Record |
| Orange | Overdub |
| Green | Playback |
| Green (blink) | Stopped (phrase exists) |
| Blue | Stopped (no phrase) |
MEMO
• The recording time is up to 38 seconds (MONO). In stereo mode, the recording time is up to 19 seconds.• The recorded content will be lost when you turn off the Looper or turn off the power.

USING THE UNIT SAFELY
WARNING
WARNINGConcerning the Auto Off function
The power to this unit will be turned off automatically after a predetermined amount of time has passed since it was last used for playing music, or its buttons or controls were operated (Auto Off function). If you do not want the power to be turned off automatically, disengage the Auto Off function (p. 9).
Use only the supplied AC adaptor and the correct voltage
Be sure to use only the AC adaptor supplied with the unit. Also, make sure the line voltage at the installation matches the input voltage specified on the AC adaptor’s body. Other AC adaptors may use a different polarity, or be designed for a different voltage, so their use could result in damage, malfunction, or electric shock.
Use only the supplied power cord
Use only the attached power cord. Also, the supplied power cord must not be used with any other device.
CAUTION
Take care so as not to get fingers pinched
When handling the following moving parts, take care so as not to get fingers, toes, etc., pinched. Whenever a child uses the unit, an adult should be on hand to provide supervision and guidance.• Expression pedal (p. 12)
Handle the ground terminal carefully
If you remove the screw from the ground terminal, be sure to replace it; don’t leave it lying around where it could accidentally be swallowed by small children. When refastening the screw, make that it is firmly fastened, so it won’t come loose.
