The NUX MG-50Li represents more than a flagship multi-effects processor—it’s a fully integrated modeling and profiling platform built for players who demand studio-grade tone and gig-ready flexibility in a single floor unit. At its core, TS/AC-4K white-box modeling recreates the dynamic response, harmonic bloom and touch sensitivity of real tube amplifiers, while DeepImage profiling lets you capture and carry the exact sound of your favorite amps and pedals. Dual-chain routing with up to 14 simultaneous effect blocks opens expansive tonal possibilities, and L/R Cyber IR cabinet processing delivers true stereo realism with precise microphone position and distance control. Powered by a triple-DSP architecture and equipped with a high-definition 5" color display, dual effects loops, stereo XLR outputs and a built-in rechargeable battery, the MG-50Li is a complete tonal command center that delivers elite-level performance whether you’re tracking in the studio or taking the stage.

TS/AC-4K White-Box Modeling With Independent Preamp and Power Amp Control

The MG-50Li’s TS/AC-4K white-box modeling engine goes beyond surface-level tone matching by recreating the behavior of real amplifier circuits at a component level. With 28 physical-model amp platforms spanning American cleans, vintage British crunch, articulate solid-state sparkle and modern high-gain saturation, the system delivers a wide tonal spectrum without sacrificing responsiveness. Separate preamp and power amp simulation allows you to pair different virtual power tube types—EL84, EL34, 6V6, 6L6 or solid-state—to shape headroom, breakup character and dynamic compression independently. The result is not just convincing tone, but authentic feel under the fingers, from edge-of-breakup warmth to tight, aggressive drive.

DeepImage Profiling and App-Based Capture for Personalized Amp and Pedal Libraries

Where white-box modeling recreates circuits from the inside out, DeepImage profiling captures the complete sonic fingerprint of real-world gear. Using the NUX IMAGE app, players can sample their favorite amplifiers, preamps, overdrives or distortion pedals and store those captures directly inside the MG-50Li. Each profile becomes a portable extension of your own rig, ready to be paired with different EQ curves and virtual power tube models for expanded tonal flexibility. With 30 onboard amp profiles and space for up to 30 user captures, DeepImage transforms the MG-50Li from a modeling unit into a fully personalized tone platform.

L/R Cyber IR Processing and Dual Routing With 14 Effects Blocks for Expansive Signal Design

The MG-50Li’s L/R Cyber IR engine delivers true stereo cabinet realism with adjustable microphone type, position and distance parameters, allowing players to dial in cabinet feel with studio-level precision. With 42 factory Cyber IRs and space for 60 user-loaded IRs, the platform offers extensive cabinet flexibility right out of the box. Beyond cabinet modeling, the MG-50Li supports serial, parallel and split routing with up to 14 simultaneous effect blocks, enabling dual-amp and dual-cab configurations within a single preset. This flexible architecture allows you to blend clean and driven tones, layer stereo effects or build fully independent signal paths—all while maintaining tight response and ultra-low latency.

Pro-Grade Connectivity, USB Audio and Built-In Battery for Studio and Stage Freedom

NUX devised the MG-50Li for real-world performance, complete with a connectivity suite that rivals full studio rigs. Dual send/return loops let you integrate your favorite pedals into either signal path, while stereo XLR outputs provide direct connection to front-of-house or recording interfaces with confidence. USB-C functionality enables low-latency audio interfacing and MIDI communication, and the included Bluetooth module allows full control through the NUX Audio app on mobile or desktop. A bright 5” color display keeps navigation clear in any lighting environment, and the built-in rechargeable battery delivers up to five hours of cable-free play. Powered by a triple-DSP architecture and premium 32-bit processing, the MG-50Li maintains clarity, headroom and responsiveness across every output.

The Flagship NUX Platform for Modern Tone Creation

The NUX MG-50Li unites physical amp modeling, DeepImage profiling and advanced routing architecture into a single, performance-ready platform. From tube-like dynamics and personalized amp captures to stereo Cyber IR processing and flexible signal design, it delivers the depth of a studio rig in a streamlined floor unit. Built for players who expect precision, adaptability and uncompromising sound quality, the MG-50Li stands as NUX’s most comprehensive and forward-thinking modeling solution to date.
