The MG-400 Creates Various Sonic Possibilities!
The NUX MG-400 is a high-quality modeler very similar to its little brother, the MG-300. The MG-400 features 2 powerful DSP chips for high-resolution white-box amp modeling algorithms (TS/AC-HD) and core-image post effects. Since the MG-300’s market launch, users have been thrilled by the sound and playability, not to mention the easy tone control and intuitive user interface.
Now the MG-400 builds on the MG-300 feature set: movable signal blocks, 12 IR COLLECTION slots, flexible P.L. block with MIN and MAX parameter setup, an extensive SYSTEM MENU, and a physical MASTER volume control – the MG-400 is now the best-value modeler for your money.
Impulse Response
The MG-400 includes multiple impulse responses with 512 samples each. You can load third-party IR files using our NUX QuickTone editing software (supports up to 48kHz sample rate). The 25 included guitar cabinet IRs combine 4 classic microphones with 3 mic positions, giving beginners a fast and easy entry into the multi-effect world.
Also included are 8 bass cabinet IRs and 3 acoustic guitar IRs, allowing you to play bass on the MG-400 or simulate an electric guitar tone with the acoustic guitar IRs.

Jack Cable
The Stage INST cables are professional guitar/instrument cables with high-quality jack plugs and gold-plated tips. This ensures low conductor capacitance and excellent audio transmission.
