Studio-grade tone sculpting, scene-based performance control, and premium picks—all in one value-packed bundle.

Key Features & Benefits

• Dual 32-bit DSP chips deliver ultra-low 1.1 ms latency and dynamic tube-amp feel on stage or in the studio.
• 25 amp models & 25 cab IRs powered by TS/AC-HD white-box algorithms for authentic vintage, boutique, and high-gain tones.
• 48 studio-quality effects—from classic drives to shimmer reverbs—chain up to 10 movable blocks per patch.
• 3.5″ color LCD & QuickTone™ software make deep editing and third-party IR loading fast and visual.
• 90 s looper & 60 drum patterns sync automatically, perfect for practice, songwriting, and one-man shows.
• Scene switching toggles multiple blocks at once, giving snapshot-style control without changing patches.
• USB-C 4-in/4-out audio interface streams 48 kHz/32-bit tracks for DAW recording, re-amping, and livestreams.
• Stereo ¼″ outputs + phones let you feed FRFR cabs, headphones, or front-of-house with separate levels.
• Road-ready chassis (289 × 160 × 71 mm) weighs under 1 kg yet houses twin footswitches and expression pedal.
• Includes 10 ChromaCast pearl celluloid picks (.60 mm) for warm attack and effortless strumming out of the box.
• Firmware-upgradable—NUX adds amps, effects, and features over time to keep your rig future-proof.

Overview

The NUX MG-400 packs pro-level amp modeling, cab simulation, and effects processing into a travel-friendly floor unit that costs less than a single boutique pedal. Two cutting-edge DSPs run NUX’s white-box algorithms, capturing the chaotic interplay of real tubes, transformers, and speakers—so every pick nuance translates into organic drive or sparkling cleans, even through headphones.

Performance & Capabilities

Each patch features 10 moveable blocks and three instantly recallable scenes, letting you toggle stomp-style layers or jump from rhythm to lead with a single press. The 512-sample IR engine supports third-party files for album-ready cabinet realism, while the 48-effect library covers compressors, modulations, pitch, ambient textures, and more. A 4-in/4-out USB-C interface turns the MG-400 into a zero-latency recording hub—track dry and wet signals simultaneously for easy re-amping.

Design & Construction

A bright 3.5″ TFT and four dedicated encoders streamline live tweaks, and the solid metal treadle delivers expressive wahs, volume swells, or morphing parameter sweeps. Gigging players will appreciate the global 3-band EQ, master volume knob, and five output modes that adapt quickly to amps, FRFR monitors, or in-ears.

Use Cases & Applications

- Home studio: record pristine DI or miked-cab IR tracks without waking the neighbors.
- Live performance: scene switching replaces amp channels and pedalboard tap-dancing.
- Teaching: 60 on-board grooves plus looper help students internalize timing.
- Content creation: stream high-resolution audio via USB-C while capturing camera audio separately.
- Travel practice: phones jack and aux-in make silent jamming simple in hotel rooms.

Why Choose MG-400?

Mooer GE200 packs 55 amps & 70 FX but costs $218 and lacks dual-DSP or scene switching. Zoom G3n offers 127 FX yet only seven simultaneous blocks and 32 amp/cab emulators. MG-400 balances 25 high-def amps, dual paths, movable blocks, and a 4-in/4-out USB-C interface—plus the included pick bundle—making it the most versatile sub-$600 solution.
