Description
NU-X MG-50Li Versatile Guitar/Bass Modeler
The NU-X MG-50Li is a powerful floor-based modeler and profiler built for guitarists and bass players who want serious tones, flexible routing and stage-ready connectivity in one compact unit.
Combining NU-X TS/AC-4K white-box amp modelling with Deep Image profiling, the MG-50Li lets you build everything from familiar amp-style rigs to highly customised dual-chain setups. Add stereo Cyber IR cabinet modelling, up to 14 simultaneous effect blocks and a built-in rechargeable battery, and you have a rig that can move easily between home, studio, rehearsal and stage.
With a large colour display, six footswitches, USB audio, MIDI, dual effects loops and balanced XLR outputs, the MG-50Li is designed to work as the centre of a modern guitar or bass setup.
White-Box Modelling and Deep Image Profiling
The MG-50Li uses two different approaches to creating amp tones.
NU-X TS/AC-4K technology uses detailed physical modelling to recreate the behaviour of an amplifier, including separate preamp and power amp stages. Deep Image profiling gives you another way to capture and load the character of amps, preamps, overdrive pedals and distortion pedals.
This gives you plenty of freedom to start with factory tones, load compatible profiles or build your own sounds around the gear and playing styles you prefer.
Dual Signal Chains and 14 Effect Blocks
The MG-50Li is built for more than simple amp-and-cab presets.
Its flexible dual-chain architecture supports serial, parallel and split routing, with up to 14 simultaneous effect blocks available for building detailed rigs.
You can create straightforward guitar sounds, run more complex stereo setups or build separate signal paths for different instruments and playing situations.
Stereo Cyber IR Cabinet Modelling
NU-X Cyber IR technology gives you detailed stereo cabinet emulation with adjustable microphone type, position and distance.
The MG-50Li includes factory Cyber IRs and space for user IRs, giving you plenty of control over the final cabinet sound going to headphones, an audio interface, front-of-house or powered speakers.
Built for Guitar and Bass
The MG-50Li is designed to work as a versatile modeler for both guitar and bass.
Its amp, effects, routing and profiling options make it useful for players who move between instruments or want one floor unit to handle several different rigs.
The dual Send/Return loops also let you integrate your favourite external pedals into the signal chain without giving up the convenience of an all-in-one processor.
Stage-Ready Connectivity
For live use, the MG-50Li includes stereo balanced XLR outputs for direct connection to a mixer or PA, standard stereo outputs, MIDI connectivity and two effects loops.
Six footswitches give you plenty of hands-free control, while the 5" high-definition colour display makes presets and signal-chain settings easy to see on stage.
An optional expression pedal can also be connected when you want real-time control over parameters such as volume, wah or effects.
USB Audio and App Control
The MG-50Li doubles as a USB audio interface, making it easy to connect directly to a computer for recording, playback and preset management.
The NU-X Audio app and desktop editor provide another way to edit sounds, manage patches and work with the unit away from the front-panel controls.
The included NBT-1 Bluetooth module also supports wireless app control.
Built-In Rechargeable Battery
One of the MG-50Li’s most practical features is its built-in rechargeable battery.
With up to approximately six hours of battery life, you can practise, edit tones, rehearse or perform without needing to stay connected to a wall outlet.
For normal powered use, the supplied 12V DC adaptor is included.

Who Is It For?
The NU-X MG-50Li is ideal for:
- Guitarists wanting a complete amp and effects rig in one floor unit
- Bass players looking for flexible modelling and routing

- Gigging musicians running directly into a PA or powered speaker
- Home and studio players wanting USB recording
- Pedal users who want to integrate external effects into a digital rig
- Players wanting a rechargeable modeler for portable setups
Our Take
The MG-50Li is a serious step up from a basic multi-effects pedal.
The combination of physical amp modelling, Deep Image profiling, stereo IRs and dual-chain routing means you can build very simple rigs or go deep with complex setups. The connectivity is equally strong, with XLR outputs, MIDI, USB audio and dual effects loops making it practical for stage and studio use.
The built-in battery is also a genuinely useful feature. Being able to practise, edit sounds or run a portable rig without immediately looking for a power outlet makes the MG-50Li easier to live with than many large floor modelers.
For players wanting a modern guitar and bass modeler with profiling, flexible routing and plenty of professional connectivity, the MG-50Li offers a lot of capability in one unit.
