Nu-X launches the MG-400

MG-400 houses 2 powerful DSP chips for high-definition White-Box Amp Modeling algorithm (TS/AC-HD) and Core-Image post-effects.

The Nu-X MG-400 is a value-packed modeler akin to his little brother, the MG-300. MG-400 houses 2 powerful DSP chips for high-definition White-Box Amp Modeling algorithm (TS/AC-HD) and Core-Image post-effects. Since releasing the MG-300, people have been blown away by the sound and playability, not to mention the ease-of-use tone tweaking and intuitive interface. And now, the MG-400builds upon the MG-300 feature set moveable signal blocks, extra 12 IR COLLECTION slots, flexible P.L block with MIN & MAX parameter setup, send/return fx loop, abundant SYSTEM MENU, and physical master volume knob, MG-400 is now the best value modeler for the money.

The white-box algorithm offers realistic playability and analog-chaos response. The concept of "Chaos makes the muse" perfectly applies to the analog circuit. When you tweak the knob, it affects itself as well as other parameters. For a linear digital system, the parameter is independent. The white-box algorithm offers real-time feedback, increment-by-increment. Nu-X TS/AC-HD replicates the same playability most guitarists crave in a real tube amplifier.

MG-400 offers 512 samples of IR, you can also load 3rd party IR files through the editor software. The included 25 guitar cab IRs combine 4 classic microphones with 3 mic positions to allow beginners an easy way to jump into the multi-effects experience. Also included are 8 bass cab IRs and 3 acoustic guitar IRs, giving you the ability to play bass on MG-400 or use an electric guitar to simulate acoustic guitar sound.

NUX MG-400 highlights include:

  • ​2.8” 320*240 color LCD with intuitive UI.
  • NG, CMP, EFX, AMP, IR, EQ, MOD, DLY, RVB, P.L | 10 independent moveable signal blocks.

  • 512 samples IR resolution and USER slot with each patch. (additional 12 IR COLLECTION slots).
  • Input trim under SYSTEM MENU.
  • Scene and Jam functionality.
  • 5 output modes with global 3-band EQ for quick tone tweaking.
  • USB recording interface, firmware update, QuickTone™ edit software.
