Amazing tone, classic design
The MG-50Li is the NUX family’s flagship multi-effects processor for guitar and bass, built around two core technologies: TS/AC-4K physical modeling amps and DeepImage profiling amp models. Players everywhere can enjoy using the MG-50Li thanks to its streamlined design, free-flowing interface, and high-quality tones.

Featuring an aluminum alloy enclosure and pedal, six footswitches, and a high-definition LCD, the MG-50Li offers a timeless, player-friendly design suitable for any performance setting. It’s remarkably simple for players to adjust the effects chain to craft any sound they want.

Authentic amps with tube-like response
The MG-50Li features our iconic TS/AC-4K Amp Modeling (White-box Physical Modeling algorithm), which is twice as complex as that found in previous versions. This led us to design a new hardware platform with three DSPs: one dedicated to handling all effects, another to running the amp modeling algorithm, and the third to supporting the split amp simulation functionality. Now we’ve even split Amp Modeling into separate preamp and power amp simulations. This means you can select different power tube models to craft unique, creative sounds.

Deeplmage amps
NUX further expands tonal possibilities with our proprietary black-box technology: DeepImage! It delivers excellent, ultra-realistic amp tones by consolidating multi-layered simulations into a single cohesive sound. With DeepImage, guitarists can load their dream amps into the MG-50Li and enjoy playing anywhere.

L/R Cyber IR
The MG-50Li features Cyber IR Technology — a true impulse response reproduction with an advanced algorithm that supports Microphone, Position, and Distance adjustments, providing stereo IR capabilities with ultra-low latency.

Parallel/Serial effect chain with 14 effect blocks
Packing up to 14 simultaneous effect blocks and ultra-flexible dual-chain routing, the MG-50Li unlocks endless tonal possibilities. Musicians can customize the effects chain freely to dial in their dream tones.

Super high quality sound
With 3 powerful NXP RT processors and premium 32-bit AD/DA converters, the MG-50Li delivers super high quality sound with ultra-low system latency, ensuring a tight and fast response.

Built to be on stage
The MG-50Li features pro-grade I/Os tailored for live use: two effect loops for your favorite pedals, stereo XLR outputs for direct mixer linking, and MIDI in/out for seamless connection to your MIDI control gear.

5 hours of battery life
Designed for freedom, the MG-50Li includes a built-in battery that lets you play anywhere, anytime—no power supply needed. It couldn’t be simpler: just plug in and play!

USB audio interface
As laptops continue to include fewer USB ports, users often rely on USB hubs or adapters, which can disrupt the plug-and-play experience and potentially cause conflicts. The MG-50Li also serves as a USB audio interface, minimizing setup time and freeing up space, allowing you to focus more on playing and creativity.

NUX Audio App control (Mobile, Win/Mac)
Patches can be edited directly from the front panel or through the NUX Audio app on your phone or computer for customization. Equipped with a high-definition color LCD display that stays readable even in bright daylight, the MG-50Li provides you with everything you need to dial in your sound and perform with confidence.
