Operating Instructions
Amp Modeling and IR Technology
The G3n features advanced amp modeling and innovative IR (Impulse Response) technology. This allows for faithful reproduction of classic amplifier tones and cabinet characteristics, providing a realistic playing experience. The multi-layer IR technology blends and activates different impulse responses based on your guitar's volume, offering dynamic tonal changes.
Preset Patches
The unit comes pre-loaded with 75 custom-designed factory patches. Each patch is a chain of up to 7 effects, amps, and cabinets, designed to recreate iconic guitar sounds across various musical eras. You can easily scroll through and select these patches using the footswitches.
Effects
Explore over 70 high-quality digital effects, including a wide range of traditional and boutique tones. From classic spring reverbs to extreme distortions, modulation effects, and wah, the G3n offers extensive sound-shaping capabilities. Effects parameters can be quickly adjusted using the four rotary encoders located above the display screens.
Looper and Rhythm Machine
The G3n includes an 80-second stereo/mono looper for creating layered performances and practicing. Additionally, a rhythm machine with 68 different patterns, ranging from metal to blues and other genres, can be used in conjunction with the looper to enhance your practice sessions.
Hands-Free Navigation
The cross-key navigation system allows you to control the pedal using just your feet, enabling on-the-fly adjustments during live performances without interrupting your playing.
Recording to DAW
Connect the G3n to your computer via USB to record directly into your Digital Audio Workstation (DAW). This allows you to capture your performances with all the effects and amp models applied by the pedal.

Troubleshooting
If you encounter issues with your G3n pedal, consider the following common solutions:
- No Sound: Check all cable connections (guitar, output, power). Ensure the volume levels on the pedal, your guitar, and your amplifier/mixer are turned up. Verify the correct output type is selected on the pedal.
- Distorted Sound: Adjust the input gain on the G3n and your amplifier. Check for any active distortion effects that might be set too high. Ensure cables are not damaged.
- Pedal Not Powering On: Confirm the AC adapter is securely connected to both the pedal and a working power outlet. Ensure the power switch is in the ON position.
- Effects Not Changing: Verify that you are in the correct mode for patch selection or effect editing. Check the footswitch assignments if you are using custom configurations.
