NUX MG-400 is a value-packed modeler similar to the MG-300, its smaller sibling. The MG-400 is equipped with dual DSP chips for high-resolution White-Box Amp Modeling algorithms (TS/AC-HD) and enhanced core effects. Since the launch of the MG-300, users have been impressed by its tone quality and playability—not to mention its flexible tone shaping and user-friendly interface.

Now, the MG-400 builds upon the MG-300 with expanded features such as movable signal blocks, 12 IR COLLECTION slots, a flexible P.L block with MIN & MAX parameter settings, extensive system menus, and a dedicated MASTER volume control. As a result, the MG-400 stands out as one of the best value-for-money modelers available today.
