Product Description

Dial in world-class guitar tones and effects on stage, in the studio, or at home with the NUX MG-400. Powered by dual high-definition DSP engines running TS/AC-HD White-Box amp modeling, it faithfully captures the feel and dynamics of classic tube and solid-state amps. Ten independent signal blocks let you chain noise gates, compressors, drives, amps, IRs, EQs, modulation, delays, reverbs, and post-effects in any order. A 2.8″ full-color LCD and dedicated Master Volume knob make tweaking presets and live parameters intuitive, while robust metal footswitches ensure reliable performance night after night.

Load up to twelve user IRs at 512-sample resolution alongside 25 factory cab/mic/acoustic IRs for ultra-realistic speaker simulation. Integrated drum machine, 60-second phrase looper, and metronome keep your practice and songwriting sessions fresh. Hook up via USB-C for 2-in/2-out audio-interface functionality at 24-bit/96 kHz or run full MIDI control for seamless DAW integration and external looper switching. Whether you’re gigging, streaming, or recording, the MG-400 puts a complete rig of amps, cabs, and effects at your feet.
