Core Technologies

Four technologies that set the MG-50Li apart

🎛️

TS/AC-4K Amp Modeling

White-box physical modeling with separate preamp and power amp simulations. Swap virtual power tubes for custom sonic textures — the way real amps actually work.

📸

Deep Image Profiling

Black-box technology that captures the exact behavior of a real amp, preamp, or overdrive pedal and stores it directly on the MG-50Li. Your rig. Exactly.

🔊

Cyber IR™ Cabinet Emulation

Stereo impulse response reproduction with adjustable mic type, position, and distance. 42 factory IRs + 60 user slots for total cabinet control.

🔋

Built-in Lithium Battery

6 hours of full operation on a single charge. Play anywhere — street, studio, bus — without hunting for a power outlet. Recharges fully in 5 hours.

Signal Chain

14 simultaneous effect blocks. One signal chain. Total creative control.

Most multi-FX units force you to choose between effects. The MG-50Li runs all 14 blocks at the same time — noise gate, compressor, modulation, amp, EQ, send/return, IR, delay, reverb, wah, and more — with dual-chain routing supporting serial, parallel, and split configurations.

Amp Library

88 amp models. Every tone you've ever needed.

Three categories of amp sound — each with a completely different approach to how the tone is created.

TS/AC-4K White-Box Models

Physical models of classic and modern amplifiers built component-by-component. Swap the virtual power tube type to reshape the entire character of the amp.

Deep Image Profiles

Black-box captures of real amps — their exact transfer function, harmonic content, and dynamic behavior preserved digitally. Indistinguishable from the real thing.

User Profile Slots

Capture your own amp, preamp, or pedal using the NUX IMAGE app and store up to 30 personal profiles on the unit. Your rig — everywhere you go.

      Also supports NAM (Neural Amp Modeler): Load third-party NAM files directly for access to an ever-expanding library of community-created amp captures.
    

Battery-Powered Freedom

6 hours. No outlet needed.

The built-in rechargeable lithium battery changes what "portable" means for a multi-FX unit. Street performance, busking, a rehearsal in a space with no power strips, a recording session in an unusual location — the MG-50Li is ready for all of it.

6-hour full battery life on a single charge
5-hour full recharge via included 12V DC power supply
Powered by 12V / 1.5A supply — compatible with standard pedal setups
Lightweight at just 2.8 kg (6.17 lbs.) for a flagship floor unit
Compact: 393 × 210 × 72 mm (15.47" × 8.26" × 2.83")
