Nux MG400 Multi-Effects Processor
The NUX 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-400 builds upon the MG-300 feature set moveable signal blocks, 12 IR COLLECTION slots, flexible P.L block with MIN & MAX parameter setup, abundant SYSTEM MENU, and physical MASTER volume knob, MG-400 is now the best value modeler for the money.
White-Box Amp Modeling

The White-box Amp Modeling & Pre-Efx algorithm offers realistic playability and analog-chaos response.
The concept of “Chaos makes the muse” perfectly applies to the analogue 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. NUX TS/AC-HD replicates the same playability most guitarists crave in a real tube amplifier.

Impulse Response

The MG-400 includes multiple impulse response of 512 samples each. You can load 3rd party IR files using our NUX QuickTone edit software (support up to 48kHz sample rate). The included 25 guitar cabinet IRs combine 4 classic microphones with 3 mic positions to allow beginners a quick and easy way to jump into the multi effects experience. Also included are 8 bass cabinet IRs and 3 acoustic guitar IRs, giving you the ability to play bass guitar on MG-400 or use electric guitar to simulate acoustic guitar sound with acoustic guitar IRs.
