NUX MG-50Li Modeler and Profiler

The NUX MG-50Li Modeler & Profiler is a flagship multi-effects floor processor for guitar and bass that combines traditional digital amp modeling with modern capture profiling technology in a portable, battery-powered format. Positioned as an all-in-one studio and stage solution, it balances deep signal routing, high-end DSP processing, and grab-and-go convenience.

Key Specs & Features

• Tri-DSP Engine & Physical Modeling: Powered by a triple-DSP architecture. One DSP handles effects, one manages amp modeling, and the third powers split-amp processing, ensuring low latency and consistent performance across complex chains.
• Dual Amp Tone Engine:
  • TS/AC-4K White-Box Modeling: Component-level circuit simulation for detailed dynamic response. Features separate preamp and power amp modeling, allowing you to swap virtual power tubes (EL34, EL84, 6L6, 6V6, etc.) to customize headroom and breakup.
  • DeepImage Profiling & NAM Support: Lets you capture the sonic footprint of physical amps, preamps, and drive pedals via the NUX Image app. It also natively supports third-party Neural Amp Modeler (NAM) capture files for access to open-source amp profiles.
• Stereo Cyber IR Cabinet Engine: Offers 3D virtual mic placement (microphone type, distance, and position) with 42 factory IRs and 60+ user IR slots.
• 14 FX Blocks & Complex Routing: Supports up to 14 simultaneous effects blocks with serial, parallel, and frequency-split routing for bi-amping or clean-blend setups.
• Rechargeable Battery Power: Built-in lithium battery provides up to 5–6 hours of cordless operation on a single charge.
• Stage-Ready Hardware: Features a 5-inch HD color display, 6 footswitches spaced to prevent accidental hits, and an integrated expression pedal.
• Comprehensive I/O: Equipped with stereo 1/4" outputs, dual XLR DI outs, dual stereo FX loops (4-cable method compatible), MIDI I/O, 1/8" headphone jack, USB-C (24-bit audio interface), and an included Bluetooth module for mobile/desktop app editing.
